On Oasis now with a 2 year old. Adventure Ocean has a nursery for babies and toddlers up to 3 years old. You can sign up (in person) for a time slot: 9 am-12, 2-5 pm, 7-1am. The daytime fees are $6/hour and nighttime is $8/hour. Well worth it! You can have them stay only part of the time (we did 10-12 the first time) or the full session. Hope this helps!
