For invitationals, we do 2 local (within an hour), 2 driving distance (2-4 hrs) and 2 travel (flights). For our travel meets, we are expected to all other sessions that teammates are competing in. Our optionals (especially 9/10s) are an exceptionally tight group of families and we usually all attend all other sessions for all meets. Even if sometimes the parents cannot stay, girls will arrange on their own, to go with another family. The girls also attend sessions for compulsory levels if they don't conflict with our practice schedule. We watch ALOT of gymnastics, lol. For States, Regionals, Nationals, non-competing team members also travel to watch the others if at all possible (not required).
The travel meets are big and held at other venues (not at host gym).
