OK, here goes.
Boat to MK
Bus to Epcot runs more frequently than the others, but we drive.
Bus to DHS is less frequent, but it would take around 30-45 minutes to get there unless you just miss the bus at the loop and depot, then mayber and hour.
Bus to AK, I am not sure.
We drive to AK and DHS.
Keep in mind that if you are in a w/c or have a stroller that driving is much more convenient because you don't have to deal with collapsing the stroller on 2 busses. If you have a w/c or
ECV and have a handicap tag, you get to park very close and won't need to take a tram. If you have a stroller, you may have to collapse if you take a tram. If you arrive later in the day, let the attendant know you have a stroller and would like to avoid the tram and see if he will let you find a parking spot closer to the entrance.
Driving will be faster than taking a bus, except to MK. But a lot of people prefer to park their car and let disney do the driving. With no stroller or w/c, I actually would prefer that.
One more thing to think about... You will put more than 100 miles on your vehicle if you drive to each park once. If you drive more than that, you are looking at 200 miles even. For me, that is pricey. Oh, and you don't pay for parking if you are staying at FW. Just make sure you have your permit in your window. Without the parking permit, you will be asked to pay, even with resort ID.
OK, I think I more than answered your question. Too much info huh. Anything else?
