Actual views aside, garden view at POR has the potential to get you a really good location if you’re interested in being closer to the main pool/building. Standard views are almost all the furthest away from those. One reason why I prefer any view (as a booking category) to standard view.
I was at POR recently and was upgraded from standard view to garden view in a great location in AB. And the view from my room was gorgeous...and with so little foot traffic that I kept my curtains open and actually hung out outside my room a few times. Others in my party had standard view. The location of my room was fantastic...a really quick walk to the pool and pool bar, boat to DS, and QS. The other rooms were slightly closer to the bus stop, but a much longer walk to everything else. I know there are some garden view rooms with not so great locations. But at least you have a chance for a good one, and I’d pay more for that chance.
