It's definitely not cheaper, but it might be easy to justify. A Moderate is $68/night more per room ($149 vs. $82) and the QSDP to DDP upgrade is $2 or $10 per person per night. If they have four Disney adults per room, the Moderate is $28/night more than Value+Upgrade. For two rooms for 14 nights, that's about $900 more with tax.Even if Pop is full there is the All-Stars. What are the ages of everyone? You might be better off booking a moderate resort then upgrading everone's QSDP to DDP.
