I have a list of things we "could" do, but I am playing it by ear. The parents may just want to relax.
Braeden was totally happy just playing with water all day long... I have a deep inflatable pool for the back lanai and will get a rigid smaller one for the front when the afternoon sun is too much. We have a pool 1/2 mile from here.
And beaches galore. B wants to go fishing ... from a boat! We have a submarine, an animal rescue sanctuary, pictures with parrots, squirt guns, bubbles, coloring books, army guys, beach toys.
I may post photos while they are here ... or you may not hear from me for two weeks!
