Hi Vanessa,
Congratulations to you and your daughter on her upcoming college graduation! What an achievement, and a great way to honor it is with a trip to Walt Disney World.
A group of seven adults can stay in a two-bedroom villa at any of the Disney Vacation Club Resorts. In terms of cost, both in Vacation Points and if you are paying with a traditional method such as a credit card, the least expensive of these tend to be either
Disney's Old Key West Resort or
Disney's Saratoga Springs Resort & Spa. Prices may vary by time of year, so do check your exact dates for pricing. Of these two resorts, I would choose Disney's Old Key West Resort. I absolutely love the laid-back theme there, and I think that the relaxing feel makes it perfect for a group of adults. Additionally, the villas at Disney's Old Key West are really big! You will get the most square footage in your villa at Disney's Old Key West, which may be useful for a large group of adults.
I would like to throw one more thought into the mix. Most of the two-bedroom villas at Disney Vacation Club resorts have two bathrooms, which, depending on who you are traveling with, may or may not be enough. The two-bedroom villas at both
Bay Lake Tower at Disney's Contemporary Resort and
Disney's Animal Kingdom Villas - Kidani Village have three bathrooms. So if an extra bathroom is important, consider those.
Have a wonderful time planning this celebratory trip, Vanessa. Please do not hesitate to ask if you have any further questions!
