If you can get out on on Fri afternoon/evening and then Sat and/or Sun, then perhaps 2x during the week (Mon thru Thur) will be enough. On other days, just do some shadow swings &/or footwork drills at home and watch some tennis videos. Do not need to do this other stuff for more than 30 minutes if you need time to for homework and other activities.
OTOH, You might want to take advantage of the good weather now, and then resume getting on the court 4-5x per week a bit before high school team tryouts start up in the Spring (I assume).
