I've done shorter, weekend trips before.  Now going for a week along the coast.  Fortunately, she has ideas and I like to plan so that works out.  But, it is 24/7 together for an extended period of time.  Any tips to keep it exciting the entire time?

I have never done that, so the following is a purely theoretical/speculative observation:

What makes sugar dating special, exciting and rewarding is that the dates are all (or should be) pure fun. A break from reality, with just sex, maybe nice meals, maybe events. But none of the drudge you go through day-to-day with a regular live in SO or girlfriend. No washing up, no messy bathroom events, no putting up with their "regular" day-to-day selves (and vice versa). Many SBs are great for a roll in the hay, but can't keep up a sustained conversation for even a few hours, let alone a week.  

So, seems to me that spending a week with an SB risks changing the nature of the arrangement.

... but I'll distill it all down to this:

 
1. Keep your plans flexible and have multiple back-ups/options ready.  
2. Plan options for a fair amount of apart time, at least 2-6 hours per day (or more - ask her), where she can get the fuck away from you.  Fund that time as well so she can do something that interests her - even if what interests her is not being with you for a while.  Be gracious and accepting when she wants to spend alone time.  (I don't know you and I'm already tired of talking to you. LOL.)  
3. Discuss key rules upfront:  
a. Who is paying for what (Hint: You are paying for everything).  
b. She can veto any plan anytime
c. She can bail any time and go home at your expense.  
d. Sex happens when you are both into it. It's never an obligation for her as your "payment" for taking her on the trip.
4. Finally, ask her to ensure she brings her own cash and cards only to be used in case of emergency. She should never be helpless / dependent on you because shit can happen (accidents, health, crime, drama, labor strikes, natural disaster, etc.).

Appreciate the advise.  Didn't plan the separate time at all.  But that may be a good idea.  Maybe some shopping time for her and I can go surfing?  Rest makes a lot of sense.  

I think I lucked into HTC's suggestion #2, plan time apart.

 
I've done very few "vacations" with SBs. Maybe five in all, and all were two nights. I might be a stretch to call them vacations.

 
Each time, without planning time apart to keep her happy, it just worked out that way. Each time, I have had work and/or meetings which require me to focus on something other than her during some chunk of the day. So I've made sure she knew when I'd leave and when I'd return, and I gave her some "walkin' around money" to make sure she could have a good time however she defined it. Most of the time she would do something with her time that I wouldn't want to do anyway, so win-win.

 
(Examples: Touring some feminist blah blah museum, shopping for essentials in Manila including refilling her birth control, wandering around some mall and meeting with long distance friends for fancy tea or something. I sent one girl on a tour of DC monuments that I would have enjoyed doing with her, but she enjoyed it without me.)

 
Maybe I'm wrong about this, but I've kind of assumed that a young SB finds it kind of hot that her man has "important things to do" while she's gallivanting around on his nickel with a promise of a hot date that night. But it has to be the right kind of girl. Some girls want all your attention, all the time.

 
Giving her some space has been a practical necessity for me, but I think it works in my favor. She gets a break from me, gets to do fun (to her) stuff, gets to imagine her man doing important, manly things, and gets to anticipate a hot date at night and any heroic story I care to tell her about my day.

Thanks for the advise, so far all is going really well!  A few hiccups.  Will give a full account when I get back.

I've just had two short vacays with SBs both both had a share of drama and the unexpected.
Especially if you haven't done overnights, you're going to be seeing all her quriks and odd habits (and she will see yours). Is she spending an hour putting on makeup? On social media or chatting with friends at 4 am? Hunting for snack foods just before dinner? Maybe she's too hung over or grumpy for morning sex? Sleeping habits may not align. Of course there could be a bunch of monetary/shopping things that you didn't plan for.  
I don't think you can plan or discuss all these things in advance but it's best to do this with someone you know well and have spent time with before.

Personally I think vacations with an SB would burst the bubble of fantasy I have with my SB's. I value my personal time and have a busy professional and home life, so I'd not be able to do vacations anyway but if I could it would be torture. I love sharing intimate time together romantically but any more than a few hours at a time would be too much. To each their own, of course. Some SB's and SD's love the vacation dynamic and spending long hours together and in some cases it strengthens the relationship. In other cases, it can lead to drama and destroy the delicate balance these relationships often walk. Too much of good thing can be a bad thing!  

After being in an arrangement for about 1 year I took my SB to Coachella. So a 4 day experience. Everything went perfectly. No drama, she was her usual pleasant and caring self. Enough sex and we chatted away like best friends on the drive and during the event. There was no time away from each other however she takes 2+ hours to get ready so I was at the pool while she did that. I guess you could say that was our alone time. I'm thinking of taking her to New York City next. On the other hand it was such a precious experience maybe it could only get worse with more trips.

Appreciate the feedback.  Mine went amazing as well!  She was great.  We did have some separate work time which helped out.  But Coachella being a festival is a little different since you have the crowd and music.

I'm exactly tuned in to your approach.  

If the girl becomes your 'paid' GF...well just do what you need to, otherwise, keep them separate.

Otoh, on a few rare occasions, with the perfect '10' ....mid 20s, double D's well then show her off!
