Ren,
I would wait to take the SBV as you have planned to give your DD time to get into a new routine. I would also plan on a time that she is alert and not fatigued. For us, 9am seemed best after a good night's rest and breakfast.
I would also suggest giving her something to look forward to in the city. I think you go to concerts and museums based on previous posts and I would let her pick her favorite place to go once you get back into your routine. While leaving the beach and friends may make her sad, emphasizing the great things the city offers may make the transition a little easier.
DD9 spent a month with my parents in Europe and nothing could make the transition home easy. Heck, I'd love to be pampered and taken to lots of fun places. But once she went back to school and hobbies started, she is excited about the new things she is learning and experiencing.
