Granted I'm not a world traveler, but I've never run across and "extra adult charge" anywhere else but the Disney resorts. I just noticed on another site that they say the Swan and Dolphin have an extra adult charge. And unlike Disney when I've booked at the Dolphin in the past they never asked how many adults. SO, if you've stayed there with more than two adults, were you charged for the extra? Did spg make any difference?
