Many banners in the streets in Legian and in villages further out. Shops and restaurants with signs saying when they would close and reopen.
My hotel also left a flyer at all the rooms about 3 or 4 days ahead - and no doubt gave it to anyone checking in after that. It had info on Nyepi, when we would be confined to the hotel, no outside lights after dark, hotel restaurant opening times etc.
The previous time I was in Bali for Nyepi, that hotel did the same thing.
These are both inexpensive, maybe 2 star hotels.
I also received an email from Smart Traveler ahead of time with information about Nyepi, since I had registered my travel details with their website.
