Welcome to the boards!
May I jump in with some suggestions for your holiday?
Last summer I had a great time in the South of Spain following my summer internship in London. There wasnt a single rainy day and temps were easily 20 degrees F warmer plus its very close to UK and you can get cheap flights especially charter flights. I did the historical route of Granada, Cordoba, Sevilla, but you could also travel along the coast to some beautiful beaches starting in Marbella. While it helps to speak un poco espanol ( a little Spanish) I found that you can often find people who understand some English.
I've also spent some fantastic times in the Greek Islands too. There are plenty to choose from depending on whether you want to "party like its 1999" or to relax on the beach or explore history. Its easy to island hop and soak up a few. I highly recommend Santorini, a volcano caldera with some of the best sunsets I have ever seen and fantastic romantic restaurants clinging to the edge of the caldera where you can go to watch those sunsets.
Finally I recommend Central Europe. I have also spent time in Budapest and Prague recently, while not as cheap as they once were, these are both beautiful cities that 20 yrs were out of reach of many Americans. Other places further east should be even cheaper.
I travelled to all of these places on a student budget from the US so I'm positive you can do these trips inexpensively.
Cheers,
