I take the term "creme de la creme" traveler to mean a savvy, experienced veteran traveler; in other words, someone that knows airport codes.
The traveler that knows not only is the museum free on Monday, but that the museum's restaurant offers a breaktaking view and serves the best cheesecake in town.
My family and friends consider me the "go to" person for travel questions. Ten years ago the most frequent question I got was, "can I get a pass?", now it's "can you book my trip for me?", followed by, "you know all that travel stuff". Oh yeah, I know all that picayune travel stuff like, "oceanfront hotel" doesn't necessarily mean the hotel has beach access, that hotel resort fees aren't always quoted in the rate and that ORD is Chicago not Orlando. (Oh yeah, some in my crew are the ones i32reds is talking about.) My aunt loves to tell the story of the VIP lounge with great food and great seats - how did she get in? some "savvy" traveler told her to flash her husband's AMEX card.
