IMHO, Harbour town at $240 a round is a little too much, when compared to what is available on or near to HH. BUT saying that , it is a chance to play one of the best known courses in the US and the 18th is a fantastic finishing hole. I got a deal to play each of the 3 courses at Seapines ( once each obviously) for a total of $305, which is still a bit pricey but if you MUST play Harbour town it takes the edge of the fees a little. THe MCI classic is played around that time of year and HArbour Town does get closed for some time prior to that tournament. The cheapest way to play is yto use "Lastminuteteetimes" you can get the phone number from the local HH phone book. You call the night before you want to play and they will fit you into a course that has availability. It would help if you know a couple of courses you'd like to play, there is alot of information on the web about golf at HH. I liked the look of the HH NAtional ( and it's right next to the outlet mall LOL) . March is peak golf season so there may not nbe that many GREAT deals about, but with so many courses you should find a few that will discount a bit.
Courses that were recommended to me, by a golf shop owner, were the "Jack Nicolas, Golden Bear", Old Carolina and Old Southern. but I haven't played them myelf.
