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.
I would plan at least a day for each:disney world, epcot, animal kingdom, mgm stuidos. if you want to do all of these, i would get the park hopper passes, they are also good for the water parks. or there is, i believe, a 2 day pass if say, you only wanted to go to disney world and animal kingdom.
