We had a similar experience last week....asked for our reason to visit the Grand Floridian. The resorts are part of WDW, and we enjoy live research on where we want to stay or not stay on our next trip. It was very un-Disney to feel like you had to sneak in vs receiving a warm welcome. That said we walked to Contempo Cafe for dinner and took a boat to WL for dinner from MK on different days. There were no problems or questions with those trips. It was just GF where we had to explain our visit. We also rode the Skyliner with no questions on one day. The second time we were asked where we were going, but it may have been to help us get there, not to screen us...it was hard to tell for sure. Resort hopping is definitely not as magical right now.
