Four 18-hole courses in order of difficulty, hardest to easiest: Palm, Osprey Ridge, Magnolia, and Lake Buena Vista. None is overly hard or overly easy. All are good courses to play. You can make tee times up to 90 days in advance by calling 407-WDW-GOLF. usually you can get what you want calling 30 days in advance but note weekend times fill sooner than weekday. Preferred grouping is four players and iif you are two you are likely to be hooked up with two others. The resort guest price per round is $105 per round first half of Jan and then Jan 18 premier season starts and it is $139
As a DVC member, you can get a discount that is usually about 35% or a little more. It applies to the member and up to three people playing with the member. Sounds great but not in your situation. Currently, and likely to still be in effect in Jan, you get complimentary clubs if you pay the full resort rate. You do not get clubs with any discount rate like DVC. Club rental is expensive, $45 per round. Thus, if you decide to bring your own clubs, go for the discount rate, if not you should likely choose the regular resort guest rate the first half of the month but the second half it is not clear whether the discounted rate plus club cost will be more or less than the resort guest rate.
As noted above they provide transportation to and from the courses, just contact front desk or valet services at the resort
