Enjoy! It's worth the time and the money. Europe has a lot to offer.
Take the trip to Paris, if possible take the bus tours they are offering. Saves you money and they show you around. I did it. It is possible to see Paris on a weekend. Believe me, you will be dissapointed, should you not take the chance.
You are going at a wonderful time, they will have a lot of festivals during this time of the year. Check them out, it will be pleasant.
Enjoy your trip and make the best out of everything, life is to short to not enjoy it.
