My wife surprised the family with a two week trip to Alaska...JUST got word of it and information on it!! Seems like there is so much to know..and..only a few weeks til!! A week land tours and a cruise...BUT what should be seen, not missed?? What should be know before going?? How much money is needed..truthfully?? Heard that 50% of what already spent..seems lika a LOT!! We are in our late 30s..looking for nature types of things NOT strenouys "Survivor" type activities...and NOT if possible costly things. THANKS so muc..I'm prepping 24/7 now for it..trying to read absorb..and from what I heard..tours and excursions are cheaper if you do NOT book them withe the cruise line but wait to you get to port. Is that true?? THANKS!!
