The people at Hoffmann's know and love their lizards. (They also have spiders, but I hate spiders, so I try my best to ignore them.) We haven't used their boarding services, but we would trust them if we needed to board our geckos.
And our cat highly recommends their crickets. He thinks they're fun and delicious.
