My beef is the people that get on the buses with people with disabilities. Okay, I know it sounds bad, but hear me out. I understand that the people with disabilities NEED the assistance. I could understand one or two people getting on with the people with special needs, but when you have 5 or more people getting on with one person with special needs, my blood begins to boil. I waited in line with my two sons, holding the younger one, for almost an hour one evening and I counted TWELVE people get on with one special needs person. It was the difference between me and my family getting on the bus and having to wait an additional 15 minutes with two kids under, at the time, the age of 7.
Ultimately, for me, it all comes down to planning. If you are going during peak season, expect a longer wait, especially at the buses. If you are staying at a value resort, again, expect a longer wait. IMO, the higher the cost of the resort, the lesser the wait due to people not preferring to pay the higher prices. So if you don't like to wait in line, especially for transportation, you have to make the proper preparations. We have driven to WDW the last two trips, so we bit the bullet and paid to park. It was definitely worth the cost.
Sorry for the length.
