Hi Gemini,
I can't believe I never complimented you on how enjoyable your shoots with TMJ are before now. Hopefully it's not too late. I guess part of me keeps forgetting that yes, sometimes even the models in the videos are people too.. lol. So, despite the fact that this is a bit late, thanks for all the videos!
As to your question: The only place I've been to in Europe is Spain. I spent a week there when I was 18 and it was a magical time. The cities I've seen were Madrid, Seville, Cordova, Costa Del Sol, Toledo, and Salamanca.
Madrid was delightful: I saw the Prado, which was an amazing art museum.
Cordova was quite enjoyable as well. It was the subject of a famous poem, "Codova: Lejana y sola." There was a lot of history behidn that city, and it was fun to look at the Moorish vs. Spanish buildings.
Toledo was the sword capital of the world. I confess I bought a sword there.
Seville and Costa Del Sol were cool, though unremarkable.
My favorite city in Spain was Salamanca. There is an amazing richness to it. The University of Salamanca, old and new, was wonderful. There was also a famous chapel that (I think) is in Salamanca. There's a frog hidden on it somewhere; if you can spot the frog, it's considered to be good luck. I can't be sure that this cathedral was in Salamanca but I do think so. Also, the Plaza Mayor has a lot of culture and shops to visit.
That's all I know for Europe, at least from personal experience.
I've also been to Puerto Rico twice; it's a great place. There are many sites to see and most of them are reasonably priced. I stayed in the Condado area, which was a good blend of old and new. If you're interested in Puerto Rico, I can post again with more specifics.
I hope you have a great vacation!
Jim
