With your first event 2 days away, you don't have a lot of options at this late date. You might try for a temporary boat to gain the skills. You can buy a used AI and sell it later (there may be one in Las Vegas (Craigs list) if you are in the Phoenix area still), borrow an older dealer demo or maybe rent one. Seems like awfully short notice!
Just guessing, but Hobie may have priority shipping schedule commitments or that the new Drive is delayed, awaiting parts.
You just got your first very important Everglades Challenge lesson. When plan A fails, have a plan B on hand and ready to deploy!
In any event, good Luck!
