The reason that there are not as many trips this year is that Uni is a small school and already has a lot of trips. I don't think that a weak dollar and high fuel prices are that big of an influence, especially in such an internationally minded school like Uni. I think that it was a coincidence that so many trips were the same year, which caused there to be fewer trips the next year due to the fact that most of these trips are long and the audience is small.
