For any 1 1/2 year old, Stormalong Bay over at the YC/BC is the best IMHO... it is sand bottom, so the children can sit in the sand & play with the buckets & sand, and you can sit in the sand with them also & help them have a little fun in the water.... When our daughter was that age, she was afraid to actually go out in a regular pool, so this worked out great for her...
