We have been going 2-4 times a year the past few years and usually stay 4 nights per trip. We also have the luxury of being within driving range so we don't have to factor in air fare. ETA: As our girls get older (1 in last year of Elementary, 1 in 2nd year of Middle School), it gets harder to go during the better times. We are being forced to go during the busier seasons, which DH does not like as much. I wish we would go to Year Round School here!
