Hi Dawn,
When my princesses were little, we stayed at the Boardwalk Inn because we are Disney Vacation Club members and this was our home resort. We could easily stroll to EPCOT and Disney's Hollywood Studios with our daughters in their stroller. I did not realize how much easier it made touring with little ones until I recommend to my dear friend to stay at a moderate resort with little ones in strollers. She said how hard it was to juggle her children and stroller at night after a long day of touring.
This being said I now recommend to guest with little ones to stay at a resort which you can walk or take a bus or monorail to one or two parks to ease your touring. To stay on budget, purchase just a Magic Your Way base ticket, shorten your stay for a day or look for deals such as free dining.
Bay Lake Towers' one bedroom will provide you with a separate sleeping area for your little ones as well as two bathrooms and a washer dryer unit and full kitchen. With the Magic Kingdom view, fireworks are right out your window plus you can walk to Magic Kingdom and take the monorail to EPCOT.
For a partial view of fireworks at EPCOT, the
Boardwalk or
Beach Club Villas are a great choice.
Hope you have a magical vacation!
