We are just back.
Tips:
Remember, you will have to change off with another adult to do some of the fun things (Dolphin swim, coral reef).
They will allow her to enter the water for a family photograph with the dolphin if you want.
The water in the coral reef and stingray pools is extremely cold. I don't know if they have little wet suits that size.
Get her used to wearing a life jacket every minute. The whole park, practically, is deep pools of water. You will be miserable if she refuses to wear one and you have to keep a hand on her every minute.
You may enjoy floating on the lazy river together, but use a float. It is very deep and you'll need to support her.
I did not see if they had any high chairs in the dining area.
She may really like the aviary if she's not afraid of birds. Ditto the ray pool.
She can meet some animals at the education cabana.
Have fun!
