We've tentatively booked a deluxe balcony suite on the Monarch of the Seas for my family -- myself, wife/mom and 2-16.5 year-olds -- for a 4 night cruise in late January. My only real concern is the weather. As an Angelino, I know It can be pretty chilly on land at this time of year and wonder about temperature difference on the water. Also, if weather is inclement, do you think there is enough "inside" activities to keep everyone occupied and happy?
