Osprey Ridge is my favourite of the Disney courses, but I don't think there is a bad one among them.
Cons for on property courses I would say LBV doesn't suit someone who's long, but a little inconsistant off the tee, a number of the holes go through OKW resort and are a little tight. LBV is better for someone who's not necessarily a huge hitter but is consistantly straight. Conversely Eagle Pines has some long carries over pine scrubby type "bunkers" but has some generous landing areas, that's probably better for the "long and (sometimes) wrong" player. If you top the ball EP can be a nightmare as once the ball gets in the scrub areas it dies and it's a struggle to get the ball out and onto the fairway. IMHO the other three are all fairly similar in terms of "golf" problems and set up, but I think OR is the most aesthetically pleasing.
Off site I think Southern Dunes and Orange County National are probably my favourites but I have a soft spot for Deer Island which is a fair old trot from WDW (I'd guess an hour's drive) but if you like playing a quiet round with few people around Deer Island midweek is an ideal place to go. Here's a link to their website

Highlands Reserve was pretty good, Orange Lake CC was fine (other than the damn mosquitos that wanted to feast upon me

), Mystic Dunes gets great write ups, Ridgewood lakes was good value and Hawk's Landing was excellent.
Something a little out of the ordinary, but I found a greast help to my game is a playing round with a PGA teaching pro, I did this a few years back and I found it very instructive and thought provoking as to how I approached a round.

Obviously in one round he's not going to try and restructure your swing (this can only be done over time and needs several weeks of lessons so is probably best done at a local course) , but he may offer some suggestions for major faults. Where I found it most instructive was an insight into how a pro "thinks" his way round a course and how to give yourself the fewest problems.
If you're fairly flexible on the courses you play and have transport I've used a company called "play standby golf" a number of times and they consistantly come up with great deals on great courses. You can only book for same day golf or for the following day if you call after 6.00 in the evening. It helps the guy making the booking if you know a couple of courses in the area that you would like to play as it gives them a guage of the standard of course you're looking for. They may not be able to find the course you request, but it should mean you get something that is in the same league.
