Semi-formal. Nice outfits. Nice dresses. Cowboy boots and attire is just fine. Even Jeans and a nice shirt!
Your presence is gift enough (:
I would consider gathering a group together and splitting an AirBnb. You could also consider some nearby Inn in Cedar Crest or hotels/AirBnb in Edgewood, NM. Edgewood is about 15 minutes from our venue. Hotels on Central and Tramway will be about 20 minutes away, however, that is definatly not the best area around ABQ.
