ask her if she needs to freshen up before going to dinner.  That way she can pick up the donation then and it won't be left in the bathroom while you are gone.  You can then go wash your hands after her, leaving the door open to make sure she doesn't bolt with the cash while you're in there.

The other thing that you can do is put a nice Thank You card (containing the donation) in a small gift bag with some nice paper and hand it to her at dinner. She will know what that is and will open it when she wants (possibly excuse herself during dinner).

About her taking off before or during dinner I say go with either suggestion but only give the money for the first hour or time for the dinner... When you get back to your place just go into the bathroom and place the rest

I would have the donation ready, maybe in a colored card type envelope.  Nothing wrong with ducking into the bathroom on return to wash your hands...  probably should anyway.  I would have the card on your person during dinner & take it out & have in your hands when you duck into the bathroom.  
Then she can use the bathroom & take as long as she needs to change & get ready.  

I wonder if she'll expect the full amount prior to dinner.  It really is a trust thing.  There are just too many scammers out there.  She uses the rest room during dinner...  and keeps on going...

When having a dinner date things change a wee bit.  Best way for your bathroom/donation concern is to meet her upstairs in your room first.  Leaving the envelope in bathroom means in your room not in a restaurant.  This is common practice and actually nice to have a minute to meet and have a hug and a kiss as a prelude to after dinner.  As far as others discussing giving only donation amount for first hour until after dinner;  if you don't trust this lady and think she may run out of a restaurant into the street leaving you stranded ???? If this is even a slight concern do not see her!  Your dinner date SHOULD be a regular date ×10 meaning, the dinner part is again the PRELUDE to dessert.  The anticipation should be all about getting back upstairs and enjoying each other.  Any fool that scams men running out of restaurants will not be well reviewed etc. Just do your homework as I am sure you have, meet her in your room first and have a quick hello and go have a great night!  

So I can check ID, say hello and put business aside.  A good idea is to ask her to come to the room first so she is completely comfortable.

She'll arrive at your hotel with a big bag with what ever extras she might need...  not the least of which is her clothes, probably a make up bag, toys, condoms.  She really does not want or need to lug that to dinner.  
So you & your date need to meet at your room.
She might want to freshen up on arrival or maybe have a sexy appetizer before you go to dinner?    
Dinner: she'll likely leave some things in your room when you go to dinner.
Return to your room for play time.  

Scammers are not in the dinner / date business generally.  I think she'll expect the donation when she first arrives at your room.  

Don't eat or drink too much which can spoil play time
