The buses are wheelchair accessible. They're smaller and older than Disney buses, so not as nice for someone in a wheelchair/
ECV. The drivers vary in terms of how helpful they are with loading/unloading. They should fold up the front section of inward facing seats for you, but when we went last June, we didn't see this happen every time. One driver was particularly unhelpful. He'd just sit there and watch people struggle, making sarcastic remarks. I sent a written complaint to the SOG manager about him. Hopefully, he's found a new career or new attitude. Sometimes the wheelchaired person was parked in the middle of the aisle. It looked like a serious safety violation to me. If you're just planning on using the TTC bus, you should be fine. It's not as busy as the other buses and runs more frequently. Every day we saw people in wheelchairs and
ECVs who wanted to go to AK or MGM being told that they had to wait an hour for the next bus, because buses were completely full first thing in the morning and at the end of the day. One day, the MGM bus's wheelchair lift malfunctioned, so everyone had to disembark and take the TTC bus to catch a Disney bus. If the lift isn't working, they aren't allowed to use the bus until it's fixed. It would be nice if the SOG bus contractor invested in some new buses, especially with the increase in guests who use wheelchairs and ECVs.
