Haha, not even a little bit.
Those white boxes threw me off. I thought the whole explore section was still under development.
Thanks for the info, sure helps to get someone to work the restaurant...
Hint: explore, explore, explore some more.
(Makes a nice chorus for a stupid song)
Apart from getting Amber and Riley, you'll find some useful items to satisfy guests (for once no innuendo, they just raise the satisfaction score in certain jobs), I think 10 pieces - after that you can for now leave the manor alone.
The woods offer a bit of content as well, only useful (but until the next update at the same time extremely powerful) thing here is the Well (after you find it, get Orville into your hotel and talk with him about it, unlocks next time). Again, for now, I am certain that the two other places you can find will have their place in the game some time.
Also, you want to explore the other hotel once to get another part time employee.
Only thing you might be dissatisfied about is that the other characters' stories aren't as developed as Julia's right now.
