We don't really do the bus service at WDW but I must say that WL does have the best bus service. My children convinced me to take the bus to MK instead of the boat once and we will never wait on the boat again. The bus was less than five minutes door to door. Epcot was maybe 15-20 minutes and on our last trip I know we did not share for Epcot or MK. The boat is nice is nice but we found long lines and often had to wait for the second boat and our trips there are usually during less crowded times.
