My daughter often complains about it being hot in there as well. usually we leave the curtains open and blast the A/C -- in the process freezing out my son who sleeps on top right next to the A/C vent. Clip on fan is a good idea!

I too have a nice fan that sits on the ledge in the bottom bunk. I wish there were an AC vent in there. I know the top has one and my daughter loves it but I usually sleep on the bottom bunk and I get HOT!
