I checked into a hotel for that purpose... and emerged three months later. Seriously, three months in a hotel room and never came out. Thank goodness for delivery.
Thanks everyone for the reply. If I can ask, for those who did, was it helpful? Also, a very dumb question (googled it, but didn't fully understand), what is a writing retreat? Does it necessarily includes a workshop or it's just someone going off for a while to write?
I've always thought of a retreat as being a place/event where a bunch of writers get together for an extended period of time to write and discuss one another's work.
