Loretta:
We have six in our family so we often find ourselves outside of Disney's ubiquitous "family of four" when it comes to accommodations. With seven, your task may seem to be even more daunting, but I've got a few ideas.
Your cheapest way to go to Disney is to book two connecting rooms at a Value resort. (Make sure to ask for connecting so there is a door between the rooms. The term "adjoining" will only get you rooms next to each other.) Two rooms will give you two bathrooms and sleeping accommodations for 8--so someone gets their own bed! The Value resorts (especially Pop Century and All-Star Movies) offer good theming and, best of all, free transportation from the airport to your hotel and from the hotel to the parks.
There's a great special on the
www.disneyworld.com website
here for free nights this Spring, but you'll need to act fast as it only lasts for a few more days.
You may also want to consider one of Disney's 2-bedroom villas. Yes, they're more expensive than the Value resorts, but with a family your size, cooking a few meals may offset the upgrade in the room. I would suggest staying at Beach Club where you can leave Epcot and Disney's Hollywood Studios easier for meals than, say, Animal Kingdom Villas that only offer bus transportation to the parks.
Wishing y'all a magical vacation!
