I agree that a pet sitter coming to your home would be best. Not every bun likes to be moved around. I would leave a sweatshirt or something for him with your scent on it for him to snuggle in. The bun should get a lot of hugs and conversation while you are gone. I heard of an extreme situation in which the owner HAD to leave a cassette tape on which she SPOKE to the bunny as if she was right there....only then would the bunny start eating. A second companion bun is an excellent idea too. Good luck.
