I guess most of the comments so far are based on rumor or stories from others. Like most private clubs Ayodhya Links is tough to get on unless you know a member. Even then a lot of the members of these very private clubs in Asia don't live there. My colleague is a member at Ayodhya but he lives in Hong Kong so only plays it a handful of times in a year.
I played it and Tony was kind enough to share my review. Yes it's swamp land, that's a fact. Rankings aside and whether it's a World Top 100 or not and whether it's the best course in Thailand or not is probably not relevant to if it's worth a visit if you can get on.
I think it's an excellent course, full of subtlety and solid to great architectural features. I thought it was really fun to play but most definitely aimed at solid players and shot makers. That being said there are plenty of tees to choose from and it's not a course to try and bite off more than you can chew. I happened to go to Thailand as an afterthought on my trip only to play this course, that's a mistake and if you are going to this lovely and culturally interesting country there is far more to see, also other worthwhile courses to play if you only want to play golf there. Incidentally the place is full of beautiful women as well but I guess that's for another discussion board.
It's a course I would like very much to play many times and for me one of the best parts was the green surrounds and green complexes, the shaping is excellent. What they have accomplished there is pretty astounding if you take into consideration the course was literally under water after the big storms a few years back and totally destroyed. Mr. Pitak the current owner redid the entire course.
Folklore would have us believe that he is the architect as well, maybe he is, maybe he isn't. He is most certainly a very nice and generous man and has a very interesting view on GCA, which I will add is very strongly opinionated so it's clearly a deep passion of his.
I think it would be a great course to be a member of. A very solid routing, easy to walk and no two holes alike. Strong set of par 3's with the token island green (which is quite an interesting hole there in the wind and certainly a fair challenge. A solid mix of long and short par 4's and par 5's.
That's my take in short. Definitely worth a visit if you are headed to Thailand. Not worth a visit if eye candy is the only thing you are looking for. It ticks the ranking box if that's relevant for you but hey you can't blame them for doing there utmost to market themselves anyway they can. If I owned a course, I do the same thing if it were possible. It's also important to realize how important these rankings are in Asia, at least in my humble opinion. Being able to say you are World Top 100 with Golf or Golf Digest for example is a huge membership draw for any of the clubs over there and worth the marketing spend required to make that happen however this is achievable.
Sean, I recommend you write them a nice letter, well in advance. Follow it up a few times. Explain your interest or passion for GCA and golf etc etc and see if you can get a game there. You can PM me if you want more information. Though I don't really have much more than my experience there. I can ask however.
