We were at WDW a month ago, and our son was 2.5 There were 9 of us, with 3 kids (2.5, 5, and 9). We used Disney transportation for everything, with no problems. The wait times weren't horrific - I think our longest wait was 20 minutes, in the evening leaving MGM.
We tend to pack light, and had a really light stroller, as well as a 2 year old that thought riding on the bus was the COOLEST thing at DIsney All of that probably made it a lot easier.
