These people helped me out of a jam some time back, so I did contracts with them for 2 trips this year. I made one reservation in August (2013) for a trip on May 16, 2014. On April 8, I got a call that they had overbooked and were cancelling my trip. My students are unhappy, and because of timing, I did not have lead time to replace them on the other trip. It will be my last with them.
