We stayed at the GP 2 years ago and went on the OL bus. We were quite suprised that a couple brought their toddler with them. It was quite "interesting" as they had a stroller. Everyone on the bus seemed to be ok with that. They let them get on first (they sat in the back with the stroller). It was in June and was it hot..the kid was a trooper though never cried or complained. That being said..I wouldn't bring a child on the bus..but thats just me. I know the GP can get a sitter arranged for you for a fee. They did that for another couple 2 years ago.
