Since no one answered my previous question I'll try and rephrase it: We're planning on Alaska cruise in July, to be combined with a trip to Yellowstone (before or after). I looked at the cruises of RC leaving from Seattle and tried to see what the availabilities are, and there are a few cruises where you can't get a Junior suite or even a balcony. Is it possible? Should I hurry and book already (8 months in advance), or I can be relaxed and book in January or even later ? We only need one cabin, but want a large one (2 parendts, 2 teens - 14 and 18 ). Thanks.
