When I moved to a new town and didnt know anyone to ask, I called around to several different vets in my area and asked them to recommend cat kennels. I made a short list of the ones that more than one vet mentioned and then called them and found out more, looked them up online for reviews/complaints, etc. After picking one that sounded nice, I went out to see it and after touring their facilities was happy with it.
Personal recommendation is good, but I think going with a vet-recommended place is also safe. The place I found rented a private 6ft by 6ft by 10ft tall area with lots of climbing areas and playthings, and a window overlooking a park for $14/day, though I'm sure cost varies by area. (this was in Wisconsin). My cat stayed there 10 days, and was happy to see me when I picked her up, but also seemed to be friendly towards the caretaker so I took that as a good sign.
Oops, just realized you may have more than one cat which gets expensive very quickly if baording, so a petsitter may be the way to go, but I dont have any tips for that.
