My wife and I are planning a first time trip to Key West in August. I am currently considering Pier House, Casa Marina, and The Reach. I noticed that the Reach and Casa Marina are both Waldorf properties (and fairly close to each other). Is one recommended over the other? Any other suggestions for accommodations? I'd like to stay near Old Town. We also would like a beach. We also want a full service hotel (restaurant, bar, etc.).
On a somewhat unrelated note, is there any reason to pack pants? I'm hoping shorts and a t-shirt work everywhere.
