I just called the resort and found out the day pass is $170 and we are allowed from 10 am - 6 pm. Lunch and facilities can be used. Since we will be there in early April we can't reserve yet and I am asked to call couple of days before as it's their peak season and they may not sell any day pass based on occupancy at that time.
I am posting it as I didn't find any recent information about this here. Also, I have few questions which I didn't find comfortable asking but if we go in there at 10:00 am will there be drinks and food we can eat or are they served at only fixed times as it's a smaller All-Inclusive? I am thinking I might take my teenage son (17) for one day so he can enjoy this cool resort.
