We'd also set up the TV there again and hook it now to our USB player. Watching our fave shows and my son's other fave cartoons at the living area with the sea breeze for ventilation will surely beat any home theater seating.
My son is even sure to have a good night and afternoon's rest all the time because of the sea breeze, plus he'd be tired all the time from all the things he'd be doing.
And I can just read to my heart's content on one of the tree houses. Talk about bliss.
