As long as there isn't a wedding going on (there will be a sign outside with all the events that day) you can even go inside and have a really good look!
It's a nice walk over to the Poly from the GF and you can even get a dole whip at Captain Cooks, and I like the shops at the Poly.
At the GF, brunch at the Grand Floridian Cafe would be really nice and I love shopping at Basin White, it's a bath store, and they have the best bath bombs!
You can also rent little boats at the Marina, that was fun one day and we got to go past the old Discovery Island and Water Country.
