I would recommend a friend first, someone your cat knows would be my first choice. If that's not possible you could ask your vet to recommend a pet sitter and have them come out a few times before your vacation to meet your cat and get acquainted.
Our neighbor is leaving to go to Hawaii in a few months and since we live next door and her kids play with my daughter she asked me if I thought it would be ok to pay my 13 year old daughter to go over a few times a day and feed her cats, scoop the litter boxes and hang out and love on them for awhile. I told her I thought it was a great idea since one of her cats is very skittish around new people and she loves my daughter. Her other cat loves everyone and would be fine if anybody walked in to feed, water, pet and love on him. I too will go over with her to help in the loving on them part and make sure the water bowls are filled to the top since one her cats is a Persian and it makes it easier for him to drink.
Since we have gotten our cats we have not taken a vacation yet. When we do, I will either have a neighbor come over and take care of them or board them in one of the top cat kennels in my area. Most reputable boarding kennels will allow you to show up at any time for a tour of the facility. They should have nothing to hide. Your cats will have to be up to date on shots and it is best to bring a few items from home like one of your t-shirts, a cat bed, blanets and some toys.
You can ask your vet about a good cat boarding kennel. As a matter of fact, I'd not only ask your vet but I'd call 3-5 vets in your area and ask them which boarding kennels they refer to see which one has the most votes from vets.
Some of the strictly cat kennels would amaze you. Some have pretty good sized rooms with beds, TV, tons of toys, huge windows so the cats can view birds outside and a person who actually goes in not only to feed, water and scoop but they have play time too. Some even have web cams set up in rooms so you can view your kitty at any given time via computer from Hawaii or where ever you are. They should also let you know that if you want to call everyday youâ€™re more than welcome to check on your cats. They are more expensive but well worth it if you ask me.
You have some time before your vacation so you might want to go and check out all the kennels in your area and surrounding area. You might be shocked at what you find.
Good luck and have a great vacation!
