Yup, DS2 said "It's too bad the worse part of our experience is other guests." AND the lack of enforcement by Disney on what is coming in the park. HUGE wagons, rolling suitcases, rolling backpacks, rolling coolers, children driving
ECV, more non-AP holders in the AP entry line than AP holders (complained in writing on this one) and that doesn't even count the rude behavior.
At Safari FP+ line two women (50's) on
ECVs ...... enter the group. The first woman quickly lifts her band, it turns blue, then she guns the ECV flying up the path with no regard for others. The second woman gets caught by CM and tells her she has no FP+. She claims she does and must since her friend up ahead got in. He lets her go. Clearly a scam which they giggled about. It was just one of MANY FP+ scammers attempting to enter lines.
Large groups (tour groups and huge families) stopping and clogging up walkways causing huge jams, EVERYWHERE. Some standing across blocking doorways and entrances to FP+ waiting their turn. It's just not hard to step aside and have your conversation without impeding others.
Constant pushing of guests trying to cut ahead in lines. With Starlord/Groot .. the queue line is futuristic

lines on the floor. Every time a group went in the family in front of me ran across all the lines trying to be next, the folks in front of them directed them back. And it happened a few times. I guess they thought at some point someone would just let them go. I was in line for a question at FoP FP+ entry and a man walked right up to my side, looked at me, then stepped in front of me and starting talking as my turn started. I just glared at him. I was inline at POP food court to check out, close enough I was next to the station ... a girl walks up with a tray and side steps in front of me - I said something (excuse me?) and she looked at me (I do have one of those faces) and she immediately stepped out and got behind me.
It's sad, it used to be I enjoyed talking with other guests in lines, laughing at cute kids and .... now it's hard to find folks even smiling and enjoying themselves. I feel so bad for CMs, I make an effort to talk to them, say something nice and be a positive in their day which there seems to be a shortage of.
