We're a couple of active, outdoorsy kiwis in our 30's, and are considering incuding an innerseas cruise in our trip to Alaska in early June. The advertising description of the cruise sounds great, but we have read one review where the average ages of guests was 60++ and alot of the adventurous side was removed from the itinerary or reduced to be very soft. Is this a typical age group and does this happen often? It's way too much money to come from the other side of the world if this is likely to be the case! We've also heard the cabins are tiny and noisy (recommended to bring ear plugs!). We're not expecting luxury, but is this the case?
