We were able to get a few more questions answered about the upcoming inns!

Will there be different layouts in different cities? Will players be able to choose specific layouts that they prefer?
There will be decorated layouts that are designed specifically for each city-state's inn, but players won't be able choose Gridania's decorations while residing in Ul'dah's inn for example. Each layout will only be available within the city-state that they are from.

Will players be able to interact with furniture? (Beds, chairs, etc.)
Yup! The proof is in the banner too! You'll be able to sit down on the bed if you feel like relaxing.

Will there be a retainer bell inside and will we be able to invite other players into our inn?
Retainers and other players won't be able to enter the inns.
