I have stayed at many Disney deluxe,
DVC and moderate resort hotels, including several times each at Wilderness Lodge and Port Orleans Riverside. My last stay at WL was August 06 and my next stay at POR is March 07.
The biggest advantage of WL over POR: the boat to Magic Kingdom which is very quick, convenient and relaxing. Other than that, both WL and POR get equal billing with me. I love both. Of course, there will be those who say "we only stay in Deluxes, and POR is not a Deluxe", and that's great for them, but as for the original poster who is open to considering a non-deluxe resort, let me tell you that POR, in almost all respects, is as good as a deluxe resort.
At POR you have a full service restaurant, an excellent and well-themed food court, a lounge with entertainment, a pool with slide plus access to POFQ's pool with dragon slide, five quiet pools, boat access to Downtown Disney on a river that winds through the center of the resort, lots of beautiful trees and vegetation, plenty of long, winding walkways, and great atmosphere whether at day or by night. The grounds of POR are truly beautiful and relaxing. In fact, although the WL is very beautiful in itself, both looking at it from the outside and sitting in the wonderfully huge lobby, WL does not compare to POR in terms of the extent and beauty of its external grounds. A great way to de-stress at Disney is to stay at POR and enjoy a long, relaxing walk through the tree-lined pathways or along the Sassagoula River, or down to POFQ, and across several bridges in between.
WL is wonderful, wonderful! WL is a beautiful hotel with great access to Magic Kingdom. But don't discount POR just because it's not a "Deluxe" category hotel. I think POR is one of the greatest bargains at Disney World. You get a hotel with grounds that are at least as beautiful and relaxing as, and maybe even more so, than any other resort on Disney property, at a moderate price. No, you don't have monorail or boat access to a theme park, or internal corridors, but POR is fantastic, beautiful, relaxing, and an amazing bargain.
