My boyfriend and I are planning a trip to Europe in May (2009) but we both have different countries we want to visit. Realistically how many countries can we see in 2 months without feeling rushed? He would like to see England, Ireland and France and I want to see Spain Italy and Greece.
I think it just depends on how in depth you want to be in each country. The first time I was in Ireland I spent three weeks on the island, which was great. If you just want to hit 1-3 cities in each country then you should be fine to do all without feeling overly rushed. If you want to be more in depth then I would only do 3 or maybe 4 countries. There's my two cents, hope its' useful
I slightly disagree with Wonkerer. I would visit 3 countries max, no matter what. A fourth country would have to be a microstate like Andorra, Liechtenstein or Holy See or just passing through for a few hours while on a train or bus from one country to another. I'm absolutely set against the whirlwind tours that are the trademark of the American tourists, the tours that string one big city and another together until everything is just a big blur.
I personally would suggest you compromise. He gets to pick one country he really wants to see, you get to pick one country you really want to see. The third one is then selected from the remaining choices by lottery and chance.
BTW, if you go to Greece, Italy or to Spain, consider adding Morocco, Tunisa and or Turkey to your list of places to see. These countries are cheaper to travel in than the EU countries and they have something truly magical to them - 1001 nights magical. UK, Spain and Morocco would be a good combination. Tunisia can easily be reached by ferry from Southern Italy, just like Greece can be reached from Turkey.
With you amount of time suggest that wherever you go set itinerary with rule: 4 to 7 nights in each place. Find aprartments/gites/cottages with a kitchens. Hang out with the real people while shopping, drinking or going to church. Enjoy!
