In order of most likely to skip:
1) (Tie) I don't do Grizzly or Tiana's period, because don't want to get wet.
2) Matterhorn because it hurts, it would take a lot for me to go ride it.
3) Goofy's Sky School because it's a horrible ride.

4) Any of the rides that are dumbo type rides (Astro Orbiter, Dumbo), because they are lame.

5) The canoes, I have never been on it, just never find the time, or it's closed.
6) Autopia, I will do if 5 minutes or less
7) Nemo, I will do if 10 minutes or less.
I typically don't do any of the above except 6 and/or 7.
rides that I would be extremely sad that I couldn't go on (i.e. it's not a successful day without these):
1) Pirates
2) Haunted Mansion
3) Indiana Jones
4) Guardians of the Galaxy
5) Radiator Springs Racers
6) Incredicoaster
7) Big thunder mountain
8) Space Mountain
9) Soarin', but only if it's california version.
Rides that are meh, either way, i.e. filler rides.
Pretty much everything else. (Note that the Galaxy's Edge rides for me fall for me here, as well as WebSlingers.)
