What is the denominator? but short answer is... YES.
you left out detail, I left out details, and I know in today's world everyone insists they are right and this is the best way and everyone else is idiots. but I'm old and still believe there is no right or wrong answer on how people chose how to spend their vacation dollars. Some people like getting bargains and fret over every nickel and get excited if they save some. saving money seems to be their entertainment. Some people just want to relax and treat themselves, budgeting is for the rest of the year, they dont want a 90% vacation, they want a 100% vacation and are willing to pay for it. Guess which group I am in?
but the discussion is on booking on opening day versus the end ... people point out Disney prices rarely go down and usually go up, but there are people that don't want to tie up their deposit money and insist you can get deals at the end, the earlier figure quoted was 10%... so the logic is, if you are willing to accept whatever deal you can find, on whatever cruise has availability, you might get 10%, or even you say 25% off, so not saving money by booking early. To which I replied and stand firm on FOR ME, thats not a vacation, I like to plan. I am picky on what cabin I get, a good view and location is part of my enjoyment... and yes I am willing to pay for that. You say, is that worth $2400? I reply, I would rather spend 9600 and get the itinerary I want, the cruise I want, the cabin I want, the view I want, then waste $7200 on whatever itinerary is on sale at the moment, with whatever cabin with the crappy view that is left over the pickings, at whatever time slot is available. That sounds like zero fun to me. So is that saving $2400? Or wasting $7200. I'd say wasting $7200. YMMV.
And, btw, I doubt seriously your 25%. I do from time to time feel spontaneous and look to see if there are any deals, there are rarely any that interest me. Maybe others are less picky. And 25% off what? The rate when it was first published, or last published? Because I bet it's last published. And prices went up. I booked on opening day an alaskan cruise next summer and it's only been 3 months... and guess what? The price has gone UP 5% already. And there is exactly ONE cabin left that is equivalent to mine. Whats the odds thats going to be left there in 11 months and 25% off. Want to make a bet? smiles. I do like winning bets. They fund my splurges. Sorry if it is against the rules to say that.
It's not just about chosing the stateroom, but everything else that goes with it. That might be a perk to you, but thats my vacation to me.
No one is right. No one is wrong. Hopefully reading my perspective has helped.
