The first few sentences of your review sound very enthusiastic and positive, though the more I read the more I am surprised about the service you received. Lots of issues...
Don't get me wrong, absolutely love that you're enjoying yourselves, however it sounds as though they are still going through some problems. I stayed at FS KOH in December 2021 and they are lucky to have a team of really kind individuals delivering stellar service. I hope the issues you mentioned (missing FSPP benefits, housekeeping spotty, missing treats at the pool, slow breakfast service, room allocation) will be ironed out.
Enjoy the resort!
