Typical of these types of sites. It's not that convenient, since I still have to call the golf course to check on maintenance status, cart path only (if it's rainy) and other issues. My biggest problem with site and others like it are:
1. They make a strong effort to peddle the 'discounted' times (these are the times they take from the golf courses for their 'fee' so it's all their money if they sell them). These are usually not the most desirable times either.
2. You have to pay 100% UP FRONT, and the only way to get a refund is if the course actually CLOSES that day due to weather. So if your schedule changes you're basically stuck (like a hotel reservation).
3. There is a "booking fee" which I find ABSURD.
4. Their selection is pretty weak most of the time.
I've been playing golf my entire life, and this type of technology really isn't welcome. I much prefer to interact with the pro shop personnel, review and select a tee time with him/her directly, and have the flexibility to change or reschedule. Use this site if you're so inclined (at least that's what the "mind control" advertising on Golf Channel will tell you to do), but for me and my golfing buddies it's a failed experiment.
