You can only pool hop if staying on WDW property on points. If you're using points for your POFQ then, yes you can pool hop. If paying cash, then no you won't be able to. Your WDW resort ID must state "DVC Member" to be eligible to pool hop, and it only states if staying on points.
I was once told no - because your resort ID will not say DVC member - I think the system has been changed - see what your ID (room key) says - if it says DVC member then you can pool hop.
your DVC member card won't work for this - your WDW resort ID must say DVC member.
If you could use your DVC member card then member staying off-site could pool hop too.
