When I'm on tour, I usually plan far in advance, so I've already got a room by the time you contact me (most likely). Especially in areas like DC, hotels can swing hundreds of dollars overnight, so you might as well get them early when you have a good chance at not losing your first born over it. If you inquire early enough, I might ask for suggestions on locations, since you probably know the area a little better than I do, so depending on how far in advance you've contacted her, that may be what happened.
But sometimes, like when I'm in my home city, I'll do the same thing - "tell me what area would be easiest" because I really am seeing one person that day, and since I'll be out and about running around anyways, I might as well let him pick the location and work my errands around it. If I'm in an area that doesn't have many drastic changes in hotel pricing, it's no big deal to see one person a day, or wait for where will work for him to book, especially if you are scheduling for more than an hour.
Obviously everyone's situation is different, these are just some general "probably happened" ones. If you've done your homework and she seems legit, then I wouldn't be put off by such questions. She probably knows what she's doing, lol
