Quick review: We arrived a couple of days early to see a little more of Munich than the tour itself does which I think was a good choice on our part. We tried out the local public transportation and visited the zoo. We found the church which has the 'devil's footprint' in it. And it's fun to just do the local thing on your own to get a feel of the place while dodging the bicyclists. ;-)
The tour itself was well designed. Fabulous hotels. The mountains are simply breathtaking, and you have a first class view of everything. I LOVED the tour of the salt mines. That was so much fun! Being in Lichtenstein was also fun. We were able to tour their Parliament and even sit in the seats which felt like getting away with something forbidden. All of the countries had great highlights, though. There was a good balance between activities and free time in almost every city.
I liked their way of handling luggage transfers. Instead of putting suitcases into the hallway, you left them tagged inside your room. That way you could still leave your personal items - last minute sweater, hat, day bag, etc., in the room and grab it before heading to the bus. And speaking of the bus, our driver was incredible.
I suggest that you pack at least two nice things to wear to dinner. Many of our included evening meals were significantly dressier than what I have seen on ABD tours.
There were two things I didn't enjoy on this tour. One of them was a fellow tourist who had to complain loudly, daily, about everything. Literally. That's always a possibility when you travel with a group, so I just mention it in passing. The other was something our tour guide did which I'm thinking might be specific to this particular guide. Every day we received a sheet with everything we were doing and the time we were doing it. Yes, I love to know where we're going and what we'll see, but I didn't enjoy knowing that we would be touring X at 4:24 pm and then Y was slated between 5:05 pm and 5:35 pm, and the bathroom break would be from 5:35 pm to 5:50 pm. Yes, the schedule was that detailed. That just made me feel stressed because it made me feel constantly aware of the time and its passage rather than sitting back to enjoy an interlude. That's a personal thing, though. I imagine many people might enjoy that.
So, yes, it was a great trip. We saw SO MANY things and places that still amaze me that I've seen them!
