Jean!
We live in Seattle and we went to WDW for our honeymoon!! We used Mears and I found no problems at all with them! Very nice driver, and we were the first ones delivered to our hotel which was CB. This time if we get to drop others off at other hotels first I think that would be great because we never had the chance or time to even SEE another resort, let alone know how to get there! We just justify a towncar or taxi for our family because we would rather spend that on our hotel room or a nice dinner. So I guess we are a Mears family until we have more kids!
BTW, make sure you have TONS of sunscreen and are prepared for the heat! VERY different from ours!
