It is my understanding that Disney's Oceaneer Club is FREE for guests (Age 3-7) and we do not have to pre-register our child for it. How about Disney's Flounder's Reef? I've read that there is a charge per hour. Now I am in my 75 day window - should I register my 6-month-old baby to this nursery? If I decide not to use the service, will I still be charged for this registration? Thanks!
