I have been told that many outdoor growers plant fall/winter crops around Dec 1, so you might be a tad early, but hopefully you'll be fine.

Dunno if leaving it on your hotel balcony (you LIVE in a hotel??) is so good, who knows who will be watching. Of course, you wont have to worry just yet, as the plants are small now. If they get big, it may become more difficult (and your neighbors might notice the smell)....

Happy growing !
