A few things that I think would just put disney a cut above even where they already are:
-A "welcome aboard" gift in every cabin. The gift would change based on how many times you have cruised. Everyone, even newbies, would have a little tray with some chocolate covered strawberries and a couple of cookies, maybe some sparkling cider. Added to that would be a little something for repeat cruises with nicer and nicer gifts the more you have cruised. Maybe a coupon for a free drink or smoothie or something like that to start and for those who have cruised 50 times or more, a coupon for a free couples massage at CC.
-All non-alcoholic drinks included in the cost of the cruise, go to any bar and soda or juice is "free"
-Better room service selections. I wouldn't allow you to order anything from the diningrooms because I think they need that in the concierge levels to help make it worthwhile to stay in those suites, but it might be nice if a more comprehensive room service menu were developed.
-mickey ice cream bars available at scoops. and real scoopable ice cream while I'm at it. As long as we are talking about ice cream, how about a "gelato social" at Palo for the adults. I am still craving that yummy fresh gelato I had in Rome.
-cost of snorkels/floats/bikes on
castaway cay included in the cost of the cruise. Basically a "no hassle" vacation and if someone takes "your" float, no worries, you can just pick up another one that has been discarded.
-if there were a production of the lion king on
DCL, I would just about die.... but while we are fantasizing, sure! Or how about beauty and the beast or Aida. Maybe they could do special "broadway themed" cruises where you get to see all 3 shows and then have meet and greets with the actors... or to be a little more realstic, how about developing a "disney broadway teaser" show where a number or two from each of the disney broadway shows are done on board. Maybe a sneak peak of mary poppins.
Of course, I'd have to raise the prices to accommodate all of that and still get my very hefty bonus (sorry, Eisner complex there for a second!)
