Yup--I live in Kennebunkport, Maine (summer home of Bush # 41) and he has SS detail full time...and not just b/c his son is the current President. I am friends with several of the SS wives and all former Presidents have full time SS detail. And from these friends I know that yes, they do book whole floors of hotels, etc. Although, as the former President gets farther away from the time he was actually in office, things do get more relaxed. They may no longer take entire floors of hotels, for example, but just take rooms on either side, etc. If Carter owns
DVC, the SS would pay for the adjecent villas (well, U.S. taxpayers would...) or however many they deemed necessary for safety purposes.
