you'd be better off staying at one of the disney hotels nearby, so that you have little travel (some are walking distance around the lake) and the tickets to the park are included in the price. they come with b&b but you can upgrade to half board to have a lunch or an evening meal which is generally a buffet (but good selection).
i have been twice and always booked direct through dlp website for acccom, and then booked gtravel separately but sometimes they have deals on that as well.
all the above depends on price of course, and going to dlp is not cheap by any means.
