thanks for the feedback. one of the big reasons that i don't want to rent a car is that i don't have collision insurance on my (old) vehicles here at home. i also don't use credit cards. so, i would be pretty much forced to buy that daily insurance for the car. i checked on this and it runs around $15 a day. that would make the car rental around $200 for the week for a subcompact.
i ithought a daily cab ride to publix or wherever would be cheaper. and, if there is some sort of public transportation that stops by cypress harbour, that is even better. i plan to chill lots around the resort and hit the parks two days. i do my own cooking, have some marriott bucks to spend at the resort, and thought that the resort probably has arranments with mears or some other shuttle service to get to disney. i called grande vista recently, and they said a shuttle to disney was $14 round trip.
if there's some sort of public transporation for under $1 or so, i don't think i'll feel too stuck.
if you have any other thoughts, let me know. thanks.
