VERY close to the airport -- you really could walk to the terminal but there is a 24 hour shuttle, which was the #1 reason I picked this particular Doubletree. The JAX airport car rental/parking lot had just had a catastrophic fire, and it was uncertain where and when the car could be returned to. I ultimately returned to the airport offisite, took the auto rental shutlle to the airport, and Doubletree was there in a few minutes (less than 5) for the pickup. Hotel room doors, etc. are dated and could use a make over but very clean. Staff was great, polite, and corteous. Made sure I received my Hilton points and cookies... :)
