Due to limited space, we hope you can appreciate that children and plus one guests are only invited if specifically named on the RSVP section of this website.
No, all venues have hard, level ground (sidewalks, brick, wood...). Heels would be fine to wear if you are comfortable in them (but certainly not necessary, we want you comfortable).
Generally, Tucson has beautiful weather that time of year. Warm days (avearge high 70 degress) and cool nights (average low 45 degrees). This should make for a beautiful day! We do recommend you have a layer to add as the sun goes down (or start dancing to stay warm! ;)
