Some might think it a silly suggestion, but since you are there for 10 nights (a long time at a hotel IMO), what about considering 5 at one and 5 at the other. Then you get to sample both and can determine your own preference first hand.
Personally I think the 1 night stay hotel hopping that some on FT do for stay credits is borderline insanity...but switching after 5 nights could be explained as totally normal!
