Like others, I've done this-when AKV first opened I booked 3 nites in a value studio, 2 nites in standard, and 3 nites in savannah just to be able to compare the three types (solo trip-so it was all part of the experience!) I never had any problem with check-out and check back in, but perhaps if I'd had little ones with me, I might have. Also, when AKL first opened, back in 2001, I booked 2 nights in a savannah view, but after the first night, I asked to be moved so I could see another savannah. Again, solo trip, so no problem with the move.
