Never ever been to Europe but we're saving up and determined to take our first trip in 2012 with our 11 year old son. We have to plan around the school year, so it's either spring break or summer, and spring break looks more affordable. We're looking at either 6 nights in Paris, or 3 nights each in Paris and Nice (through European Destinations.) For first-timers, which trip should we do? What are the advantages/disadvantages of traveling to Paris and Nice in March?
