As an Albuquerque resident, I'll get the suggestions rolling. RV and Motel reservations fill up quick. Book a spot as soon as possible and cancel if plans change. Same goes for the area campgrounds.
A TOAD makes many more things convenient. Public transport to the fiesta grounds is provided by either the RailRunner train system and the local school buses are enlisted for Park and Ride services from places all over town. The Park and Ride doesn't change much from year to year and can be used planning RV locations.
The Balloon Fiesta is very dependent upon the weather. Add flexibility to your itinerary by planning to stay in the area for the week but not necessarily at the fiesta grounds in case the weather forces a change to your plans. There are many mountain camping opportunities (RV park and primitive) within an hour of the fiesta grounds. There are some beautiful places accessible with your rig.
If you'd like more specific suggestions of places to stay and things to do, please feel free to reach out.
Regards,
Cliff
