I also noticed some of the cast members asking odd number groups if the "minded" sitting with a single rider. While it seems like a nice touch from a PR standpoint, it got pretty annoying on a busier day when the single rider line took more than 20-30 minutes to get through (only slightly faster than the normal line). My philisophy is if someone doesn't mind riding by themselves and there's an empty seat available, that seat should be filled. People who don't want to sit next to a stranger should not go to a theme park.
I completely disagree! New, popular attractions should not go out with empty seats if there's a body to fill them. I've never seen people asked before riding MM, and that counts single riders at ski resorts going back many years before the concept even came to theme parks.
I avoided tips on this ride before my maiden voyage, and intended to check for tips online before riding again that trip. Unfortunately, no connection at our hotel, and no wireless to be found at the DLR (unless I just never asked the right person). Still got to 169,000. Bookmarking this page for next time.
