Drs. Foster and Smith prefer to vaccinate puppies with a combination vaccine at six weeks of age initially, with boosters given every three weeks until the puppy is about sixteen weeks of age. We feel that this schedule will help protect the widest range of dogs.
If, for instance, you are planning four days in Disney, and you plan to spend one full day touring each park, a park hopper pass is probably a waste of money. However, if you are unsure exactly what your disney park schedule is going to be, purchasing the park hopper could be good insurance.
The Park Hopper option is an extra charge per ticket, and allows you to go from park to park as many times as you want during that day (Magic Kingdom, Epcot, Hollywood Studios, Animal Kingdom). The Water Parks & Disney Quest are not included, but Water Parks can be added on for an additional price.
