I found it interesting that a video RCL put together for our recent farewell show had lots of clips of people doing lots of different shipwide activities and events, but not a single second was devoted to any of the ports - arrival, departure...nothing. So I can see where for those who truly cruise for the cruise itself (meaning a greater interest in what activities are on the daily cruise compass moreso than where the ship is going next) probably are more apt to select a cruise based on the ship rather than itinerary. Certain destinations, perhaps, are more of a 'traveler's' cruise. When we were in the Baltic, I think it's fair to say that the destinations were the main draw, let alone even more adventurous locations like Antarctica where a whole suitcase (or two!) might be devoted to really good photography equipment (we saw evidence of such). An onboard lecturer excitedly comes into the windjammer during lunch and refers to an albatross off the port side, for example, and everyone gets up from their tables and heads out on the decks to get a look! Totally different type of feel to that cruise compared to the average pleasure cruise down in the Caribbean, which we also enjoy.
A few other thoughts...The whole 'cruise director' thing is totally lost on us since we don't get involved in basically anything that he has anything to do with. Only time we see that person is on stage in the theatre to introduce shows.
The whole tier / points structure is interesting as well - all geared to getting people to sign up for more cruises to attain that next level! We sat in front of a guy at an ice show who was a solo traveler and was telling people next to him that he can't wait till he's Diamond (after that cruise) so as to be able to use the lounge, etc. Since attaining Diamond awhile back I think we've been in a (card access only) lounge like 3-4 times total. Just not into it. Others, I'm sure, make it a point to go in there and get their evening cocktails before dinner. Something onboard for everyone's taste and preference I suppose.
Fascinating psychology, I've always felt, is associated with the cruise industry and surely the lines know how to play to it to their advantage. Viking, for instance, successfully advertises as appealing to "curious travelers". Very different sort of cruise since you don't have the many varied activities and entertainment options that some people are looking for. Once again each to his/her own.
