I'm sorry, but yes it is so. I have stayed at the Epcot resorts twice. Both times with the same result. The bus service was horrible. You may have had better luck, well good for you. But to say that my information is false because you haven't experienced the same is just ridiculous. If you want to let the OP know you have had better luck, fine. But your experiences don't somehow negate the experiences we have had. Oh and by the way, we "ALWAYS" shared busses no matter how busy it was or what time of the day. In fact, one of our stays at BCV was during Thanksgiving week. Why do people take it as a personal attack if someone dares to say something negative about their favorite resort. Heck, my favorite is AKV, and I will be the first to tell you that the bus service there leaves something to be desired. Notice I didn't recommend AKV. Why? because their bus service is suspect, and the OP clearly stated that bus service was a priority.
I suppose it all depends on each individual's experience. As I said, I primarily stay at BWV...my home resort. So, I think I have more experience than most. I have yet to find that any one resort has superior bus service. In fact, I seldom recommend, or recommend against, a particular resort based on it's bus service. That's just a bad idea. Why? Simply because there are going to be those that have had, in their opinion, bad bus experiences, while someone else, there at the same time, may feel that their experience was wonderful.
I once stood outside Kidani...waiting for a bus to DHS. One had just left as we were walking to the bus stop, so I figured it would be about 15 or so mins before the next one came. There were no other people at the stop...waiting for any park bus, just my friend and I. As time went by, people started arriving. Well, we saw the bus to DHS coming along, so we walked over to where the bus would stop, but back a bit in case there were guests getting off. Well....there was a woman, with a group, who seemed to take exception to the fact that my friend and I were standing there. She yelled, at the driver, 'Hey, we've been waiting for at least 30 mins and we should get on first!!!" Ah, no....first of all, you got to the stop about 10 mins ago (we watched, we saw you arrive) and the last bus left about 17 mins ago...so how the heck did she think she had been there for 30 mins??? The driver ignored her. We got on. My point??? People seem to have different views on busing and wait times. I've stood there, listening to people say that they've been waiting forever. Now, I doubt anyone thinks 9 mins is forever!!! But being a moderator on the Transportation Board, I tend to take note of times at bus stops. Most people tend to exaggerate their wait times. Not saying you did....but it happens.
Every single resort is going to have some type of transportation issue. I'm not saying that there are not people that have had bad experiences with the Epcot resorts and buses. BUT.....before they say how awful these resorts are, regarding buses, have they actually taken rides on other resort buses?? To compare? I have. My one ride back to OKW from Epcot took forever!!! Much longer than any ride back to BW..except for maybe a trip or two home from DTD!!! I mean, seriously...we were on that bus for almost 20 mins after we went through the OKW gates. Granted we were the last stop but man, it took forever.
I mean no disrespect here...as I said, everyone has their own experiences. My issue is when someone says that a particular resort has miserable transportation...especially the buses. So, yes, I do come along and give my opinion. RescueRanger has given his experience from the two times he has stayed at Epcot resorts. And I'm sorry these were not good experiences. But, in all reality?? I have stayed at Epcot resorts at least 20 times....all of them, but mostly at BWV. Have I had less than stellar experiences with buses? On occasion. But nothing that would make me stay elsewhere. If I based my resort choices on bus experiences? I wouldn't stay at the Polynesian, OKW, VWL, AKL or SSR again!!! All provided me with not so wonderful bus experiences. The best? Pop!! Never once had an issue with them.
So, I apologize for ruffling any feathers here. I really wasn't saying anyone was 'wrong' but that their statement didn't give the entire picture. Many, many people keep returning to the Epcot resorts...I guess they don't have the same issues with buses that others have had.
