Ireland/Amsterdam/Germany/Switzerland/Italy-First Europe Trip Itinerary

[runswithwolves]

Heres my itinerary for my first trip to Europe! It isn't set in stone so let me know what you think or if I should add/subtract anything. I know it is a lot to try to fit in but I've never been to Europe before so I'd like to see as much as possible (without spending all our time in transit of course)...do you think we are trying to do too much? I'd really appreciate any input :-)

-fly into Dublin-
Dublin-2 days
Wicklow Mountains/Glendalough-2 days
-flight from Dublin to Amsterdam-
Amsterday-1 day
Cologne -2 days
Koblenz area-1 day---We want to spend one day either driving or taking a river tour of the towns along the Rhine River from around Cologne to Koblenz...if anyone has any suggestions for this part of the trip or if you think we should spend one day in Cologne and two days driving or floating along the Rhine, this is the part of the trip I am still a little undecided on so I'd love suggestions!!--
Interlaken area-4 days-we want to do some hiking in this area and we will also be taking a side trip during this time to Grimmelwald
Cinque Terre-2 days
Rome-2 days
-fly from Rome to Dublin and then Dublin to home-
