Information on the
DVC member golf discount can be found on the members site. Look for the the Member Benefits Handbook?
A DVC member can get a 25% discount for pre-10 a.m. times and 40% for post 10 times. The discount is off the resort guest rate and not the higher day (off-site) guest rates. How much the discount actually amounts too varies among seasons. The high price season is about mid-Jan to end of April, low season May thru Sep, and mid-season Oct to mid-Jan. Rates are published on-line at the Disney World site (google disney world golf).
To qualify for the discount, the member must purchase an annual DVC golf discount card for $50 plus tax. You purchase it at any of the pro shops at the courses. You can make tee times up to 90 days in advance and usually you can get what you want by calling about 30 days or more out, 1-800-WDW-GOLF. The member and up to 3 guests playing with the member get the discount. If you have less than four they automatically hook you up with others to try to make four.You can reserve DVC discount times before you get the DVC golf card.
Whether you should buy the card and get the discount depends. If you are only going to do a round a year, the discount won't make up for the cost of the card. Also, if all you are going to do is pre-10 times, you should check into the two day discount that is offered to any guests staying on site. You pay for two rounds at once and golf on different days. That discount is often very close to the DVC discount per round, making it the preference for pre-10 times many times of year because you don't have to buy any annual card to get it, but of course you have to play an even number of rounds (you can buy multiple two day discount passes).
There is a 30% discount if you have an AP but that is 30% off the day rate and thus is not as good as the 25% DVC discount but you don't have to buy any card in addition to your AP. You cannot combine any two different discounts such as DVC with AP when getting a time.
You can rent clubs but it was $45 for steel and $60 for graphite clubs per round sometime back and might be more now. If you fly Southwest, there is no additonal charge for clubs. I believe other airlines charge the same as they do for any bag and thus taking them with is likely to be cheaper than renting particularly if you play more than one round.
There are four 18 hole courses, Palm, Magnolia, Lake Buena Vista, and Osprey Ridge. There is also a 9-hole executive course, Oak Trails, which is walking only. All the courses are good. Osprey was by far the best but there so much construction going on around it right now that it has lost some of its luster; it is where the new Four Seasons resort will be. The Magnolia is the one used for the pro tournament held there in Nov. Lake Buena Vista, which runs through OKW and SSR, is the easiest of the four although none is overly easy or overly hard. If you do not have a car, free taxi rides are provided from and back to hotel, although you need to tip.
