Hi Katrina,
Several years ago my side of the family, all eighteen of us, traveled to Walt Disney World together. We had a great debate on where to stay so I completely understand your dilemma. If you are looking for the most cost effective solution, you might want to start with a budget and work from there. Deciding on the budget might make the decision for you!
We also looked at location because we had a family member with mobility issues. After looking at budget and location, we also decided we wanted a kitchen or kitchenette to be able to have breakfast before we left the resort. We ended up staying in two two-bedroom villas and one one-bedroom villa at
Disney's Beach Club Villas. It was a bonus for the kids to have a splashtastic time at Stormalong Bay.
Please let me know if I can help you with any other questions.
Wishing you and your family a magical vacation,
Amy H.
