Should I go on a free trip to san antonio, tx or play in the baseball district tournament?

I am in band and everybody has done fundraising to go on a band trip to San Antonio, TX. We will go to Sea World and 6 Flags. This trip is scheduled for April 28 through May 1. The baseball District Tournament is April 29 through May 2. If I go to the trip then I will miss at least 2 games and possibly 3. I am a Sophmore starter for the Pottsville Apaches and I'm one of the best if not the best player on the team. If I go on the trip my coach told me that I won't get playing time for the 2 weeks before the tournament in order to get other guys ready to take my spot while I'm gone. If I go to the baseball tournament then I will miss 3 days of a free ticket to 6 flags, Sea World, and swimming parties with pizza that I could not otherwise afford. What do I do?
