We're planning a trip next June. Pretty sure of the dates, unless something changes with too many snow days to extend my school year (I teach), or something with kids college schedules (internships???). My question is this...If I book now, using just the AAA rate (which I'm pretty sure I can get now), will my chances of getting a PIN code for next June be affected? I'm hoping to get some kind of better discount than AAA, but I'm afraid if I'm already booked, I'll get booted out of the system for PIN codes. Any thoughts on this???
