aerospace engineer, I can tell you that the 747 had fancy bars, etc., in their interior sketchs also. Most airlines are trying to move people cheaply -- which means cram them in. Other than for the Ultra First Class passengers, I doubt anyone else will see those fancies.

The casinos will probably be similar to the on-line versions, using credit card & video screens, and sub-let to some supplier. No Chips.

Consider how long it takes to load and unload a 737. Now think about tripling the amount of time you have to stand in line to get on and get off, not to mention check in and baggage collection.
