Hi S.,
I organized a school group through the group sales dept. We ended up with the 174 then add the tax etc. You need 10 rooms or so as a minumum but check your kids friends families then let each figure out how to split their room.
Another option is for you to get the family suite then just have your sister drive down to "visit". You are allowed to have 30$ guest passes for one of the days you are there.If you are paying for 4 in your room then 4 can pay the 30 each to swim for the day, 5 paid for in room can get 5 30$ passes. We considered having visitors come with us to check in, buy their passes for 3-9 or 10, sort of sneak stay the night then go home the next am.They can't swim another day though.
