When I think advanced recreational class, I think kids that could be on a pre team or getting ready for one. I would inquire politely to the front office/program director or coach? Honestly, some rec programs don't have a month to month or session schedule.
With girls at that level, we always hit floor per week and bars. We did a bit of dance every other week, but not the entire time on floor. Generally beam every other class and I liked to switch tramp/trak/vault.
This also depends on what the class is scheduled for and if team is getting a priority of time and equipment which could be the case.
Most rec classes don't need to be on anything past a medium beam and skills wise, honestly a low beam. However, it is good to get them " up " there on medium or high beam to deal with the different challenges they bring. As most rec kids do not have a solid handstand, it doesn't make much sense pushing it to beam when they can hardly do it on floor or say the L3/4 dismount.
Getting back beyond spealing, girls need to hit bars maybe the most of all the events, especially early on. Most younger athletes will be lacking upper body strength for it so they need to get on it. Working beam and floor won't get them that unless they are conditioning on bars and rope.
