Bob, tie down space is plentiful and is located in front of the terminal building (also where LuxAir, the FBO, is located). Their number is 623-932-1200 if you want to call them ahead of time with questions.
I don't have my March schedule yet, but I should have Friday 1 Mar off. If so, I can pick you up and drive to the game with you so that you don't have to rent a car or take a taxi. Let me know if this would help.
By the way, the offer is open to anybody else who wants to come down for a game. I highly recommend it. The stadium is superb, and the weather is always perfect for spring baseball!
