Just found out my first year is going to be as a floater teaching 2.5 preps… any advice?

2.5 bc I'm teaching 2 preps but one of them has both a 90 minute every other day and one has 50 minutes every day.

Trying to stay positive, but I’m very disappointed that I’m not going to have my own classroom, especially for my first year. Has anyone been a floater before and have any advice?
