I know you can take kids of all ages on a cruise and that they will enjoy it. My youngest isn't yet 3 and is getting ready to take her 3rd cruise. So far we have done an Eastern and a Canada cruise out of NY. Our cruise in March is also an Eastern to San Juan. I would love to do an Alaskan cruise. If we choose to do Alaska in 2014 my girls would be 4 and 8. Would you recommend waiting until they were 5 and 9 or even later for Alaska or do you think it would be fun to take them at 4 and 8? I know it is very subjective. I guess I'm curious how your younger preschool age kids did and what kids of excursions they enjoyed? A lot of the excursions in Alaska are pricey so I want to make sure they could be truly enjoyed by a small 4 year old. I also eventually want to do Europe either via cruise or via a land based vacation but I'd like to wait until both girls are older to take that trip.
