Most flights into New Mexico are routed through Albuquerque which is roughly a 50-minute drive to Santa Fe. There are both shuttles and a train, but a car will certainly be the easiest form of transportation to Santa Fe. For the duration of the weekend, parts of Santa Fe are walkable and rideshare is also an option. As for the wedding, transportation will be provided to and from Santa Fe Plaza and the wedding venue.
Welcome drinks is casual attire. Come as you are! Wedding dress code is Cocktail Casual. Have fun with and be comfortable in whatever you decide to wear! Dress for the summer heat and desert nights. No ties needed (but bolo ties encouraged). For footwear, be mindful the ceremony will be in desert terrain.
New Mexico is high desert climate. Prepare for warm days and chilly nights. Please also be mindful of the altitude in Santa Fe. Be sure to drink a lot of water and prepare that certain substances may impact you a little more than you're used to!
