Okay, I've come up with a more finalized list of cities after researching each on the web.
1) Paris. It looks like a very nice city and english speaking bike tours look like they will be fun. I'm sure the nighlife isn't bad either.
2)Mallorca. After looking at photos, the beaches look awesome, hiking through the hills looks like fun too and I'm sure clubbing is the best you can find. Plus it's an island!!!
3)Amsterdam. It's a must. Let's see... red light.. coffee shops... rich history/culture. you get the picture. Plus, dad lived there in the sixties so he's cool with me going.
4)Munich. It's a Bavarian city that looks like fun to explore, and I hear bavarian food is excellent.

Dublin, Tallinn, Copenhagen, and Budapest are all great suggestions and I want to go although I only have sixteen days to travel before I am staying in Poland, so I think Mallorca, Paris, Munich, and Amsterdam offer a good variety.
