So - was there this weekend (Thurs - Mon) and had a few observations.
1) Weekend crowds are SUPER heavy. The difference between Friday at EPCOT and Saturday at EPCOT was crazy. Saturday mid-day we weren't even allowed to join the queue to get into the Mexico pavilion. Most of those folks were waiting to get to the bar, but they didn't branch people between bar/ride until close to the front of the queue.
2) Too many snack carts are closed. Wait time for ice cream cart at MK was 30+ minutes (the only place to get a Mickey bar in Tomorrowland was the popcorn cart - with an ice cream dedicated cart sitting closed right next to it). I could only find one cart with Mickey pretzels at HS and it ran out at 10:45am with no replenishment for a while. Disney is leaving a lot of money on the table just based on guests not being able to easily buy snacks.
3) lines, lines and more lines. Lines for snack carts, lines for rides, lines to get into stores, lines to pick up your mobile order (Cosmic Ray at MK was particularly bad for this)
We had a large party of AP coming from out of state. one family is wishing they had gotten a refund for the their AP. I'm a die hard and I'm wondering if it was worth being near the parks on a weekend.
