Would any of you experienced European vacationers out there be so kind as to share your advice about the tour? =) I'm going in July and the tour stops in London, Amsterdam, Rhine Valley, Engelberg, Innsbruck, Venice, Rom, Florence, Nice, Lyon, Paris.

For some destinations, the attractions are obvious, but can anyone recommend highlights for any of these locations? Optional excursions?

Any advice on what to bring, weather, etc. would be great too. =) Do we spend a lot of time traveling in between destinations? How are the buses?

Thanks everyone!!!
