I have been looking around at several topics. Not ready to bother a travel agent yet. Don't know what questions to ask or what to look for. looking maybe at an alaska 7 day cruse with princess in Aug. (too soon or to late to start?) Just picked princess as a starting place. Why are some cruses and ships cheaper than others ( island princess vs. sapphire princess ) ( $600. vs $1200.) Both go to the same place a few days apart. Both get to Whittier at 12:30 AM, do you get off at that time or wait untill morning?
I would try to pick a ship/itinary and get in touch with a travel agent and see what space is available. Alaska cruises fill up quickly, so by seeing now what there is, may help you decide which one to do.
