Tenant wants me to wait 2 weeks before I can show an apartment.

[Elena Pech]

Hi,  my first tenant decided to move out at the end of her lease. According to lease agreement I can bring prospective renters with a 24 hour notice. I asked her today to make showing on Saturday, (6 days in advance) got response that she is too busy and can do it in 2 weeks. She is a good tenant, but obviously she doesn't care about my needs. I have 14 people waiting to see an apartment, and with lease start on June 1st, they most likely won't wait for 2 weeks. What would experienced landlords recommend to do?
