How much time is reasonable to respond to an email if you are an instructor?

[soliloquy]

I am in the final stretch of my Capstone. I will be finished in 7 days. :hurray: I submitted draft 3 of my capstone on July 1. I asked for her to review it and send me changes before the long weekend so I could work on the last draft over this weekend. My instructor has praised the fact that I turn my assignments in on time (frequently ahead of time).

I have not heard from the instructor since July 1. I know it is a holiday week but there was still July 2 and July 3 before the holiday came. I forwarded it to her again on July 1 just in case she didn't get it. I really wanted to be finished with the last draft this weekend but because she won't respond, I am forced to wait until whenever she decides to get back to me.

I think if you are going to be an adjunct professor you should either respond promptly or let your students know if you will be out of town. I understand that there may be computer problems (although generally they don't tolerate these excuses for students) or health issues but if I'm paying over $1,000+ for one class, I expect some sort of feedback.
