Smiling Hotel - Hell's Hotel / Heaven's Hotel

These are more for demonstrative purposes, and you can probably do better than this.

Heaven's Hotel is fairly straightforward.
Chen Gong can replace Shakespeare as long as you have Arash' Mana Loading unlocked.
You do need 500 ATK on the CE on Arash, if it has no beneficial damage effects. Similarly, Euryale can use any 50% starting charge CE with 2k ATK. (Not all of that is needed)

Hell's Hotel on the other hand, is the worst. I would strongly not recommend doing this, because it's essentially a one CE setup.
Again, Arash can use any 50% starting charge CE with 2000 ATK. Chen Gong might need Sun-Princess, but it is the most recent one, so it should be fine.
Medea can be replaced by basically anyone with a damaging NP, as long as they can fully charge themselves.
Euryale and Avicebron both need Mana Loading unlocked, and in the case of the former, slightly leveled. Avicebron also requires his Anti-Berserker Append unlocked and leveled.
