Do I need to let Sonnet know if I’m going away on vacation?

No (but we’d love a postcard). However, if you’re planning on being away more than two weeks, make sure you have someone stop by periodically and, in the winter, ensure that the heat is on. This is especially important since damage resulting from frozen pipes bursting isn’t covered under your policy if you’ve been away more than 14 days and haven’t had anyone checking on your home.
