Collecting data · Fall 2026
Cruise upgrade bidding is a blind auction. You name a number, and nobody ever tells you what it took to win.
We are collecting what people actually bid and what happened next — the wins and the losses, which is the half nobody tracks. Log yours and you will see the clearing price for your ship before you bid again.
Pick the line first — the cabin names on the next screens come from that line.
Ship, cabin, amount, timing, and what happened. Ninety seconds on a phone. Losses count double — they are the half of the market nobody records.
One number per ship and upgrade path — the median winning bid, its middle-50% range, and the sample size behind it. Medians only, never averages.
Type your intended offer and see where it lands against everyone who came before you. Then go bid on the cruise line's own site. We never touch the booking.
A card like this for every ship and every upgrade path, updated the moment a new result comes in.
Every figure we ever publish shows the number of reports behind it and the date it last moved. Where the sample is thin, we say so instead of guessing.
Clearing prices by line, the biggest bargains, and the win rates — monthly, starting January 2027. One email a month. Nothing else, ever.
You bid on the cruise line's own site. We do not bid for you and we take no payments.
We store a sail month, not a date. Nothing here can be traced back to your booking.
Under five reports and we show the raw results instead of a median, labelled early data.
No brand will ever pay to move a median, a ranking or a verdict. That rule is the whole product.
