If you are going in June, be aware of "price slice," meaning after 10 a.m. the price of the courses goes down -- for Eagle Pines from about $90 to $55.
The five 18-hole courses are Palm, Osprey Ridge, Eagle Pines, Magnolia, and Lake Buena Vista. The degree of difficulty is also in that order (with Osprey and Palm being about equal in degree of difficulty). None is overly difficult or easy. Osprey is by far the most impressive course there with the most memorable holes and two of the best finishing holes you will ever see. One thing to be aware of as you struggle through the first difficult 13 holes is that 14 through 18 are much harder. It is also the most expensive, followed by Eagle Pines, and then the other three are usually the same price. Magnolia is the longest course but has very wide fairways (and the Mickey shaped trap on No. 6). Palm has the narrowest fairways, lots of water, and Palm trees that literally eat balls, it has the feel of a very old course. Lake buena Vista runs through the OKW resort and has a minimum number of tricks.
Eagle Pines is the shortest course but it is a lot of "target" golf particularly around the greens (lots of traps and often water close to the green). It also has many sand waste areas running up the sides of the fairways (you can ground your club in those). The course is a Pete Dye design and is probably the easiest Pete Dye designed course in existence, which simply means it is not as impossible to play as the courses that he usually designs -- he loves to put 450 yard par 4's directly into a prevailing 25 mile an hour wind but avoided that at Disney. The course is very pretty and you feel isolated while playing because you see nothing but golf course and swamp forests while playing (and often an alligator); both it and Osprey (its sister course) are designed so that you are farthest from the clubhouse on the 9th hole and then return on the back nine -- thus you only see the clubhouse at 1 and 18, but there is a refreshment cart (fully stocked) that usually comes every four holes. They sell course books at the clubhouses. Highly recommend you buy one and particularly look at size of greens. The greens are very long there -- some up to 50 or more yards -- and thus that back pin from the 150 yard marker is really often 170 yards away and that front pin only 130 so it is easy to over or under club unless you have the course book.
Have eaten breakfast at the Sand Trap and it was fine -- fairly large space for a golf course restaurant.
