We spent 2 nights here for a wedding last month and found the place to be wonderful. Despite some construction going on by the pond and in the other wing of the hotel, we never heard any noise from it and were not bothered by it. In fact, the construction was probably a factor in getting an exceptional rate of $199/nt, so we had no complaints. The grounds are beautiful, the lobby is incredible, our room was outstanding in every way, and the service was perfect. This is the only hotel that I've ever been to where I was greeted at the door, handed a drink, and led to a couch where the check-in paperwork was brought to me!
We took the shuttle to town a few times to get a cheap meal and also took it down to the other 4 Seasons hotel hang out at the beach and at their much better pool. Being allowed to use that resort's facilities as well was a great benefit. In fact after we checked out and waited for our late evening flight, we took the shuttle to the beach for the rest of the day and then were allowed to use the spa facilities to shower and change.
After 2 nights we did start to recognize that maybe one more night would be just about our maximum before starting to get bored, so a 3 night stay would have been the perfect length for us. So if you're looking for a secluded, romantic, and quiet getaway, this is the place. And now (summer 2006) might be a good time to score a great rate while the renovations are going on.
