Adrenaline Peak - XL - Test seat out front I would recommend trying, the corners of the lap bar can hit riders with big hips as it is curved around the edges but allows for a lot of belly room
AtmosFear - L - Automatic restraints come down and can be a bit tight for those with large shoulders or chest
Carousel - XXL - This features bench style seating so anyone can ride
Cosmic Crash - XL - Fairly large bumper cars most adults should be able to get on with an over the shoulder seatbelt strap
Disk'O - XL - Zamperla ride that has motorcycle style seating in which the restraint closes on your back allowing for ample room
Ferris Wheel - XXL - Surprisingly one of the few ferris wheel rides I've been on that allows single riders so you should have plenty of space
Go Karts - XL - A rare free go kart attraction has single rider or double cars available for nearly all to ride
The Train - XXL - The train cars can be a little bit tight for tall riders but all should be able to get on
Rock & Roll - XL - Matterhorn attraction has a lapbar that goes over both riders. Single riders may go alone
Raceway - DNR
Rock-O-Plane - L - Our rider hit his head on the top of this ride every time it goes around. It has large enough seats for larger riders who are heavier but those who are above 75" may struggle
Rockin' Tug - XXL - Designed for families with just a lap bar that comes down over the whole row, anyone should be able to ride
Scrambler - XXL - Singles may go alone on this ride allowing for ample ride space
Spider - XL - Really tall riders may have to go alone and cross their legs in order to get car door to close (I did the same) however other than that this has a ton of space
Tilt-A-Whirl - XXL - Lapbar only that really has no restrictiveness and should allow almost any adult to ride
Tree Top Drop - S - Our rider did not fit on this ride and there is a weight limit of 220 lbs.
Up Up & Away - XL - Spinning style tower balloons attraction ride has seatbelt only in cars that go up and down while spinning around
Zero Gravity - M - Riders who are large or have big legs may struggle to get the belt to latch on this ride across the cage pods. I was very surprised by how difficult and close this was to not reaching
Zoom Coaster - L - Kiddie coaster has decent amount of room for adults if you ride alone
