Here's an example to answer your question: We went last December for five nights and six days, with another family: 4 adults and 3 kids. We got two 2-bedroom villas off-site for $300/week each through Interval International, and one night each at CSR, POR, and CBR for 1-2 adults and 3 kids. The total for food and lodging came to about $1800. If we had stayed on-site and gotten the dining plan for only one room, it would have cost us $3200 with the dxdp and $3000 with the standard dining plan. If we had stayed off-site and paid for food out-of-pocket, bypassing the resorts, we would have spent about $2000, but then the kids couldn't have swum in the resort pools or rested in the rooms. Also, we would have saved more had we had planned the trip more than a month in advance when standard rooms were available, but instead we could only get water-view and preferred rooms.
