At most places no, you do not need to be a guest at that resort. Specifically, what resort are you asking about?
I was looking at Poly, for example, but most resorts have a full "recreation" sheet that tells you activities going on. Like, scavenger hunts, movies, games, etc.
No parking needed. Just using Disney transport. Thanks though!If you are driving parking at the Poly can be hit or miss as the lot there is tiny. They may tell you to park at TTC and walk/monorail back to the Poly.
