Yep, it is fun! Everyone stops and says "aww can I see your dog!" Also bring a comfy bed/pillow for them.. Because they just stay in this hard plastic blue box thing.. We brought both our dogs, and for my parent's pug, they didn't bring him a bed and poor thing was probably uncomfortable in that box..
There is also this little garden thing next door where you can take your dog to do it's business. The CM that works there will not take you dog out to if they go to the bathroom in their box, even if there is poo poo everywhere.. So we went and took our dogs for a walk every couple hours..
