Welcome to Disney Secrets, Trish! We're glad you've joined us! :)
Congratulation on your first stay onsite at WDW! It's a terrific experience at all levels of resorts!
We (my BFF since age 7 and I) used the DDP once and enjoyed the opportunity to try TS restaurants we might not visit otherwise, but we felt tied to our ADRs! As two very middle-aged females, we also aren't accustomed to larger meals--although she handles them better than I do! --so that was an issue after about the fifth day.
Other than that, we pooled our remaining snack credits the day before our departure and she purchased a lot of the Rice Krispie treats to take home to her grandchildren and other family members. She packed them in her checked bag and they arrived at her home safely.
Biggest DDP tip: Don't overeat just because the food is there!
