You must have had some bad luck. I was there mid November and rode almost a dozen times with a single stop of 30 seconds (and a second close call of a 30 second stop right after we got off).I enjoyed the gondolas as an attraction. Mid November still not reliable enough to count on as transportation but I believe it will improve. Stuck out there twice for 20~30 minutes did get old, something I have not experienced on buses boats or ferries. But when operating correctly the long queue is walked through in a few minutes and loading of carts and wheelchair is glide on simple. Stroller people could use some practice
The restrooms are near the load points. Given the stalling of the gondolas frequently my advice is always use the restroom proactively. It isn’t like a bus you are likely to miss the next gondola is only seconds behind.
I did experience a 30+ minute delay on a bus though when a charter bus that Disney called in for MK closing got lost when a section of road was closed near pop century. Felt bad for the guy, but we had to give him directions. Gondolas, hopefully, can't get lost
