We were just there last week with five children of all ages. The youngest is 20 months, & her favorite things were taking bike rides & walking along the beach. I think when you are going, dog owners can only have there dogs on the beach early in the morning, but our DD absolutely loved walking up & down the beach in search of doggies to watch playing...most of them were most happy to share kisses with her!

Since the weather will be warmer for you, you could really get some enjoyment from days at the beach. Sand + Water + Kids always seems to be a winning combo! (My DS (9) was thrilled to have a shovel & just started digging holes. Don't you know, he came out of one BIG hole with a HUGE, BEAUTIFUL seashell...the kind you pay money for in souvenir shops!!
As others have mentioned, the Shannon Tanner show in the summer is a must (not there in off-season

). Another thing is they have a ceramics place in Coligny Plaza where you can pick out something to paint. They just need two days for glazing/firing. They had some smaller, fairly inexpensive ornament type things & the owner also suggested doing handprints on a plate.
You will have an awesome time! One thing we have discovered at HHI is that you don't need to over plan (like WDW trips). Sometimes the simplest bike ride, walk on the beach or digging in the sand becomes the greatest adventure. Enjoy your trip!!
