I agree on the more of Juliet. Right now she just seems to get belittled or always just seen at the store or the school. Her visiting the hotel to see Ash or Maria or even the twins would be cool. Maybe have it be something like Hana and eventually, unofficially or not, "moves in", as Kali did as well.
I doubt Runey's going to add a 3rd floor, but that's where all the girls like Hana and Juliet could go, maybe even Lucia. Doubt that's ever going to happen but would be cool. I'm just curious who's going to move in to that final 2nd floor room; Vanessa, Hana, Kate, shit even Moon would be fucking awesome to have in the hotel instead of a side character. Her and Lin together? Oh yeah!!
