We currently go 7am - 2pm for summer band with a 20-30 minute lunch break.
Mainly we do 2 90 minute sessions outside. Then we spend about 90 minutes in sectionals and 90 minutes in full band with lunch and breaks in between.
For those of you that go longer (let's say 7am-4 pm), what other sessions do you have? We are ok with facilities and staffing is not a huge issue.
