Yeah, it sucked, but it could have been a lot worse. I'm one of those 'never sick' people, too.Oi! So sorry you got sick on the first day!! It's really rough being sick when you're not in your own home. I'm glad it only lasted one day, and you were able to start enjoying your ABD.
I felt fine the rest of the trip. I was glad it wasn't during our pre-trip - we were constantly moving from place to place - or on a travel day.
A few others missed some excursions later in the trip. Some felt ill halfway through our day - ABD was great about getting them alternate transportation to get them back to the hotel to rest.
