I once attended a wedding reception in a nice airport hotel. It was one of the nicer ones I attended, you could not hear the airport at all from the reception hall (which was, admittedly, in the basement), and valet parking was included if you stayed the night (I drove up, there was no direct flight so it did not make sense to fly, especially with the wedding proper being off-site).<p>I suppose that highlights the issue versus a wedding: many people want to attend the ceremony, too, and depending on your preferences that might not be doable at the hotel, at which point transport is required (though it could be a rented bus).
