We're supposed to be @ The World right now, but an unexpected illness forced us to postpone the trip three days before we were to leave, and as a result, no Mods were avail, and we decided if we are postponing, we are rewarding ourselves and upgrading to WL (our first Deluxe,) rather than downgrading to POP (only other property we've stayed at,) and, since our trip at POR was already paid for.
Anyway, with that being said, I will give you my usual logic on this discussion. I can typically stay at POFQ for about half what a Deluxe would cost. So I always come back to the question, would my kids prefer going TWICE, or prefer to stay in a really nice hotel once. And you can probably guess the answer to that question, and frankly, I'd rather go twice too!
Now, given that we are going to WL for the first time, in Nov, I suspect my opinion may change...but just another idea to weigh when you are considering.
