There will be seven of us, 2 Grandparents, Aunt, 2 Parents and Two kids (5 & 8) for five nights this X mas holiday season. I looked at the prices on the website and it doesn't seem as if Disney's resorts are competitive with what can be rented off-site very close to the park. Is there any price advantage at all of staying on-site versus off-site? Given the times we're more budget focused this year. Thanks.
