i've never tried an illuminations cruise. i'm thinking of one for 2/1 if still available. should i worry about cool temps, cranky overtired babies, etc? i have 2 DDs - 6 1/2 mo. & 2 yr. 10 mo. w/ 2 adults to help out. should i attempt this or wait until they're older? their normal bedtime is 8:30 but i'm thinking they may enjoy a boat ride & watching the show even if they're tired. OR i am better off letting them view it +/or sleep in their stroller. what do you think?
