The looks of it, yes it seems like off-site guests are. It was even harder to get reservations for a party of seven for A&E as well as SDMT, but I ended up getting those with serious determination. I was refreshing and checking the
MDE website every hour at least.
The only thing my family is worried about is Be Our Guest Lunch & Dinner. It's been something we've wanted to do. The Lunch seems to be the issue for us, but we are going to try and get there early for it. I've not surprised my family though with finding two reservations (one party of 3 and another party of 4) 15 minutes apart on our last day for the BOG dinner. I'll be doing that our first day down there.
It's more trying to be persistent and determined for it, i guess. It's why I definitely advise all off site guest to continuously check fast pass and dinner reservations. They do appear up often.
