Here are my experiences with bus service, courtesy coaches, pools, housekeeping, conventions (and more).
BUS SERVICE: The transportation to and from the theme parks rocks! In my experience, it blows the POR bus service right out of the water. The wait for buses was usually between 1-10 mins and surprisingly, that includes the buses from MK to CSR. We only had to stand on a bus once from MK. Even though we caught the bus to the theme parks at bus stop #1 at El Centro (the last stop to be picked up for theme park transp), we always found a seat.
CSR's central location is a huge plus. It never seemed to take too long to get anywhere, including MK.
Only once did we experience a bummer of a long trip. That was when we wanted to go to Typhoon Lagoon in the very late afternoon. Typhoon shares a CSR bus with downtown Disney. So when we got on the bus at El Centro (bus stop #1), we had to make the trip around the entire resort picking up and dropping off guests. Then we had to go to downtown Disney Market Place, then Pleasure Island. From the time we got to the bus stop at CSR bus stop #1 til we got to Typhoon, was about an hour due to traffic, DTD crowds, and bus stops. Because of this, we only got to spend about 45 mins at Typhoon Lagoon, but that's what we get for leaving so late in the first place.
About POR.. I am not dissing POR. I will always have a special place in my heart for POR as it was our first onsite stay back in 97. And although I find POR has the most beautiful grounds, the bus service there is severely lacking. Plain and simple, they need more buses!
Buses in general: There were a few times from MK that we felt the bus driver was driving too fast. I noticed this more on this trip than on any others. I thought it was just me, but I heard others mention this as well.
