My godparents who live in Vero Beach came over and visited us for a day in Oralndo. They came in the late afternoon, and we just had them come over to the condo, we had a few snacks and visited at the resort. Walked over to the pool and sat out there for a while. Then we heading to the Polynesian Hotel where I had dinner reservations for all of us at Ohana (it was really fun) and we hung out a little at the lobby and the grounds, headed back to the condo for a little more visiting (watched an NCCI basketball game with team we were all rooting for), and they were on our way.
We really just did the same things we'd do at home with a nice dinner at a Disney resort added in.
