We have had our reservation for quite some time now. We rented one week at Silver Lake Resorts. We have a 1 bedroom, full kitchen unit with a pull out sofa. It is my husband, myself, our 10 &11 year olds. Tonight our daughter and her boyfriend said they would like to go with us just to go away ( ages 21 & 23). While we are ok with it the room we have sleeps 4. We are driving and the kids wouldn't mind a bit to sleep on a blow up mattress. The room is considered a 4 person unit. I haven't called yet to see what an upgrade to a 2 bdrm would cost if they even have one available. My question is if they do not have one available or the cost difference is outrageous could we get by doing the above scenario? we are leaving in 2 months! Will the staff not allow us to stay? or will they even notice?
