My husband and I have taken many Disney cruises and a few alone. We always felt it was very nice for just adults as well. We just booked another cruise on the Disney Dream for September 22nd! It will be our 30th wedding anniversary and felt this was the best way to escape into warmer weather now that we live in New England again <husband works in Boston> I do not think its creepy to be on the ship without kids. The adult only area and the spa is a wonderful place. There are many kids but they never bothered us as we always found a place to be without them. We booked a balcony so we are planning on some peaceful time there as well.
