How long will you be gone for?
There is a place (breeder) where Kian was for the past 9 days while we were in the US.
She is a bit of a drive but she will train your dog as well as kennel your dog. http://pointblankdogs.com/
Here's another vote for pointblank.
We were really pleased with them, and super impressed with Liz's training!.
They are a bit of a drive, it takes us ~1:45 from the city, but you'll probably find their rates a little cheaper than the average boarding kennel.
If it suits you better, we also used Dogs at Camp once. The owners of the Cooksville location own a Vizsla themselves, so Mischa was more than welcome there. They have a great facility that is a lot of fun for the dogs, but they won't do any bird training like Pointblank will.
Trust me your V will have fun. If you haven't done any field training or hunting w/ your V, it's a sight to see. It's what they're bred for. They love nothing more than hunting for birds. We visited Liz at Pointblank when looking for breeders, haven't taken Mac there for training yet, but she's a very well known trainer, and I would imagine it would be the ultimate vacation for you V. Field training/hunting is a V's ideal type of fun!
