I'm doing some research for a spring dive trip to Florida and have heard good things about Conch Republic. I'd like to stay at a Marriott or Hilton for the trip so that I can use hotel points for part of the stay and earn points for the other part. It looks like the Marriott is about 11 miles away from Conch Republic. Ordinarily, 11 miles wouldn't be a big deal if we have a car (which we will), but I'm wondering if 11 miles is too far to drive when you're dealing with a single road environment like the Keys. I realize that the Marriott won't be as convenient as staying at hotels in the immediate vicinity, and I'm ok with that. I just don't want the location to be a major hassle. Thanks
