I started another thread here (Where are some tourist traps) but I dont think I got my point across in the thread.

Im trying to plan a vacation for December and would like some recommendations.

Here are my past vacations and what I really liked about it. (maybe you can recommend some stuff based on what I enjoyed)
Italy (Florence and Rome) - been over 15 years so I dont remember much...but I liked the museums, Vatican city, coliseum, I think Pompeii.
San Francisco - Golden Gate bridge, Science museum, 100 steps, steepest hill, Fisherman's Wharf.
San Diego - Lego Land (awesome!), Sea World
Vegas - Penn & Teller, walking around the casinos, Star Trek exhibet, the Pirate show thats free - saw that twice in 3 days. Would have liked to go to Cirque de Solei and Celine Dion.
Miami - airboat ride, Coral Castle (thats it, the other times were spent on the beach, which I find boring)
Paris - Eiffel Tower, Louvre, Arc, walking on the Champ, Notre Dame, Invalides.

So as you can see I like the "touristy" type places.
People recommended when I was in Paris, to just sit and eat some cheese and wine and relax. I rather skip lunch and keep looking at stuff.
When I was at the Louvre, I wanted to just walk around the whole time, but my gf had to stop for lunch and then a snack. (we went on the day it closed at 9pm)

So any ideas on some places? (I dont drink and not a fan of clubs/bars/parties)

From my other thread, it sounds like theres a bunch of stuff to see in London and Rome.
But my gf has been to London twice and Rome once.
So that might be a tough sell to her.

She mentioned Galapagos island...but I am resistant for 2 reasons:
1. Whats to do there? Look at Nature? We work so we dont have to be THAT close to nature, thats why we live in a building and not in the woods
2. It seems like a LONG flight from NY. We only have 6 days, so its not worth spending 2+ days flying.

Thanks
