You'll LOVE POR! My husband and I go alone many times and stay there (we like all 3 moderates though, hard to choose!). The POR has beautiful beautiful pathways, you can take romantic surrey ride or walks along the river. You can take a boat ride, as you probably know, over to Downtown Disney, its very romantic. We just love POR.
PS OOOPs sorry, didn't see the last post. If you do go to values, you'll still be happy there, particularly your child, a 4-year-old is going to have a real blast. Great for the money, you can't touch a regular hotel by us for those prices. You can also keep an eye out for codes on mousesavers also if you want to upgrade to mod for romance, but with a small child you can't lose there. We are super mod fans but we aren't bringing young children either.
