I had a chance to chat with some writers last night, and one of the topics was writer's retreats. One of the writers takes turns with other writers in her region to host a retreat every three months. Another writer talked about renting homes, in particular, Rudyard Kipling's home. It has ten bedrooms and rents for $700/night, which isn't bad if you split the cost among ten people.
I haven't done a writer's retreat yet; it can be difficult enough just taking a couple of hours to hang out in a coffee shop or the library. But I wouldn't mind the chance to go somewhere scenic for a few days and perhaps stay at a bed and breakfast.
Have you ever been on a writer's retreat? Did you go by yourself or with other writers? Was it productive? Feel free to share your experiences in the comments.
