The hop-on-hot-off was confusing. There were acturally 3 different tours and a 4th for people going to cruise ships only. This needs to be explained better in your advertizements. But other than that - the tours were good. Not as much hop-on-hop-off as we had expected. We thought we'd be able to get on and off at any intersection but there were designated locations. But still good. Nice having bus language channels.
