Sorry, but 30 minutes is not an exaggeration and calling it that is being dismissive of other people's experience. Here's examples from our last three trips. In Dec. at OKW we WAITED for an AKV bus for 50 minutes. Then it was 15-20 minutes or so travel time. Our last stay at WL it was an 18-20 minute bus ride to Epcot twice, not including wait time for the bus. 35-40 minutes total trip time. Also in Dec (and I'm not speaking of the Christmas holidays) our trip with wait time to MK from BCV was almost 1 hour on the nose. I would not be at all suprised if 30 minutes is more of an average when you consider walking to the bus stop, waiting for a bus and the travel time. Many locations are 15-20 minutes travel so all you are talking is 5 minutes walk to the bus (which most places are) and then a 5 minute wait for the bus (which is just a matter of luck and timing). In May my DH left AKV 1 hour 45 minutes before my nephew and I did. We rode Everest twice, Primeval Whirl once and Dinosaur once. Then we headed out, caught a bus (after a 10 minute wait) and arrived back at AKV 20 minutes after my DH. It took him over 1 hour to get from AK to AKV Jambo house.
This quote if from Wikitravel "The buses are reliable, fairly efficient, and reasonably comfortable, but they can be slow and inconvenient if, for example, you are traveling with young children or strollers. Expect to wait up to fifteen minutes for a bus to your destination, and another ten to thirty minutes to get therepossibly longer during the busy season. Also keep in mind that guests in wheelchairs have first priority when boarding. "
And another source on travel from WL/VWL:
"Travel time based on touringplans.com data (including waits) are:
DAK 37
DHS 37
Epcot 32
MK 19
DD 52"
Many people are having an enjoyable time with friend and family and don't even realize how long it takes to get from point A to B. I actually have next to no complaint and am not a whiner about the transportation - always a proponent, but also a realist. I don't feel our experience has been anything but the norm and only posted this to share another example. What has been stated is not trying to justify an argument - it's happened to me and it's happened to others. When you walk at DL then there's zero wait time and the speed is just as fast as
you can motor.
-----------
For the OP's questions - I'll vote a tie!
For BLT: approaching 50% sold, greater sales base (+), greater number of points (-), competing against 2 other locations at WDW for sales (-), proximity to the busiest amusement park in the world (+).
For GCV: I'd guess it's getting closer to 50% sold, smaller sales base (-), only DVC on west coast which is both a plus and a minus, proximity to second busiest amusement park in the world (+), proximity to two amusement parks (+), large local base for visitors (-).
Actually, If I had to make a choice I'd say BLT but I think DVD is trying to even it out with the price differential. If the GCV were plopped down at WDW all factors being the same I don't think there would even be a comparison though - it would win easily. IMO.
