I'm planning a weekend in San Diego including a trip to Sea World. Sea World advertises the availability of kennel space for your doggie. Has anyone here used these kennels? How many do they have and do they fill up? I would hate to get there and then not be able to get in simply because they had no space in the kennel for my Karly. Also, are they kept clean and cool? I know to bring her bed, food, water and some toys. I'll walk her on the leash a couple of times during the day. I almost hate to leave her like that (my fiancee calls her "my daughter") but it seems the only alternative if we want to visit Sea World.
