Vacation ideas needed

Justin & I will celebrate our 15 year wedding anniversary in June.  I would love to take a quick trip somewhere - I'm thinking 4 days maybe?  We are already planning a Disney trip this fall but a nice little get-away would be great.  Will most likely take the kiddos.  Any suggestions?  Justin let me know the Cubs are playing that day - yeah...just what every wife wants for their anniversary!  Now I'm not saying a day at the ball park isn't a blast but come on - this would be like receiving a power washer for Mother's Day.
