The distributed ticket is a sure thing, but the STEP ticket might not happen, I suppose. Of course, I'm sure you got your STEP mojo working, so you should be okay? If a camp is offering a direct ticket, they have probably paid for it already and just expect you to reimburse them, probably with some additional requirements. Are the tickets being mailed directly to the camp in June, or held at will call? Does the camp require dues? Are they asking you to be there a day or two early for set-up, and maybe stay late for break down and clean-up? All reasonable, I think, considering these tickets are intended to help camps get the help they need. Depending on the camp (many aspects to consider, beyond curb appeal) and your willingness to get really involved, I recommend the direct ticket and camp unless you're already set up with some kind of group. Then you can cancel (possible?) your STEP and give up your place in line to the next burner.
