The post can be a single image, an image gallery, or a link to a specific comic hosted on another site (the author's website, for instance).
The comic must be a complete story.
If it is an external link, it must be to a specific story, not to the root of the site.
You may post comics from others or your own.
If you are posting a comic of your own, a maximum of one per week is allowed (I know, your comics are great, but this rule helps avoid spam).
The comic can be in any language, but if it's not in English, OP must include an English translation in the post's 'body' field (note: you don't need to select a specific language when posting a comic).
Politeness.
AI-generated comics aren't allowed.
Adult content is not allowed. This community aims to be fun for people of all ages.

Ugh, getting everybody moved will take forever!

Considering this simple case, it will take just the time for the slowest guest to move to the next room as they can all take their luggage and move to the next room that should be vacant by the time they reach it.

However, this is considering a magic comms system that lets all guest know to move a room instantly. In the case this is not available, the speed of light is the limiter and then it takes forever.

Using the case with instantaneous communication, it is possible to take forever by trying to host a countable infinite amount of people as this is usually done by moving the original guests to the room that is double the current one and the new guests to each odd number left. In this situation, the original guests will take forever as for bigger numbers, the guests have to move more and more rooms each time.

Sorry for the rant, I've seen too many Hilbert hotel videos

Perhaps the hotel staff bring in a guest each day at a preset time. They just have to all move rooms at 5pm.
