Ask questions, meet dancers, and be part of the conversation.
Also depends on what you feel you can accomplish in the time slot you give yourself. While I feel 45 minutes (or even less) is sufficient for solo practice, I would typically want 1 hour or more if practicing with a partner.
But generally agree with davedove, the fewer days between practices the better. And that goes for learning most anything.
I have wooden floors too in some parts of the house, but I am terrified dancing in shoes on them being afraid to leave scratches, so I dance in socks, which is not the same obviously. Yes I have heel protectors, but do they really help with scratches? Besides, my instructor doesn’t believe in practicing at home, he says I need to practice at the studio to adsorb the vibeI have wooden floors at home and even though it's far from being a dance studio, there is definitely a lot that I can do there. Even a very small amount of practice daily makes a big difference. If you can get into the studio and do a longer session, terrific. If you cannot, find even 10-15 minutes of material you can practice at your home and it will likely help.
