Yeah, but there is a limit to the price the market will bear. At 10k users and assuming a single terminal, and a single price, you are going to not going to be able to price it so as to optimize price vs performance.

Personally I would have at least 2 terminals, a low tier and high tier. I would sell only a limited number of high tier connections, good for the entire trip. Probably included as a perk with first-class cabins. The low tier would be a daily purchase. I mean hotels have done this for ages.

Maybe a dedicated business center with wired (dongle) connection and kiosk PCs, that gets the best bandwidth of all, but you're away from ship activities.
