My husband and I are here now, it's our last day. We arrived Thursday. I've worked at Disney during Easter, been here over 4th of July and Christmas and Jersey week. I was so excited to come in September for "low crowds" but we honestly are a bit disappointed. MK was a total zoo last night. I understand it's because of EMH and the Halloween party, but seriously it was like a summer weekend crowd. It was nowhere near a 1, 2, 3 or even 4 that most calendars had posted.
We are here on our babymoon, I'm 23 weeks pregnant so in all honesty we were napping at the hotel during the afternoon. Evenings in the parks was when we had thenough least luck with ride times.
However I do know that there were a ton of conferences going on. Most deluxe hotels were at 100%. We are at the GF and it is at 100%.
If we go in September again I'd go 1 week later, or maybe not over a weekend.
FWIW, DHS was pretty manageable today. We are just waiting for our dinner at Beaches and Cream and are ending in Epcot before heading back to the GF to watch the Halloween party fireworks and head back to reality tomorrow!
