We recently spent some time at the subject resort in mid-February. Out of the 7 restaurants there, three of them offered gluten-free options. The Concierge (sp?) was very helpful and gave us a copy of a listing she had generated of gluten-friendly restaurants within a few miles of the resort (at least 5 within walking distance). Their deli had a wide variety of gluten-free potato chips, and snacks.
I'll admit, it was a pricey vacation, but we had planned on it being expensive. The only place off-resort I cannot recommend is Silas Dents. I believe hubby got glutened there, on day 3 of the vacation, and pretty much ruined the rest of the vacation.
I would go again, but next time, I'd fly instead of drive. The time in the car, plus the time cooped-up in the room was a bit too much "togetherness!"
But, the first 3 days were glorious!
