One of the things I like about Disney transportation is the ability to converse with other passengers. My daughter loves to meet other kids. The one trip where we stayed off site with a car just didn't have the same magic.
Any BW veteran knows there is but one thing to do while waiting for a boat to show up.......Eat.

Nothing like a fresh pastry, ice cream cone, slice of pizza, etc. to tide you over as you wait for the boat.
Its funny about Disney transportation. Each visitor has a different take on it, and it really comes down to luck. When we were at the BWV and WLV last month, we never waited longer than 5 minutes for a boat or a bus(except one late night for the boat from MK to WL) and no trip took longer than 20 minutes. Then you have people back that say it took 45 minutes to get home by bus, etc. It seems timing is everything.
I'm like others on here that don't like to fold up the strollers. They are like moving lockers, filled with all our stuff. One evening our daughter fell asleep in the stroller on the way to MGM by boat. We rolled right off the boat, I went on TOT and RNR while my daughter slept the whole time(DW is pregnant, so she sat and people watched). Not having to get a sleeping child(or tired one) out of the stroller is a big plus for us. Thus the love for the Epcot resorts.
