I would switch for the extra money. Convenience is what you get at WL, and that is worth the money for me. Cause POR is in the DTD area it is much farther to the parks especially to the MK. Plus its about 5 bus stops within POR-FQ, compared to two bus stop, sometimes and GF and sometimes at FOrt Willderness for WL. POR-FQ combined has over 3000 rooms compared with WL with just under 850 rooms. Meaning if you trying to catch a bus there will be alot more people and headaches getting on the bus. We stayed at CSR just this past week and we saw the lines for POR-FQ and they were incredible. Cause CSR is a convention resort there is not much people going to the parks. That just doesn't mean on the buses but lines at the food court, conceirge etc etc.
Everything is in one building at WL, you also have two table service resturants, you have interior hallways, a balcony where you can unwind on especially if you have a great view. Have you stayed at either or? I have stayed at a deleuxe and just this past vist stayed at a moderate and there is just a whole different level of experience.
Cause POR is a moderate resort it has exterior hallways, so for privacy you have all of your curtain drawn and its really hard waking up in the morning without natural sunlight coming in cause your windows are drawn.
I would switch not only for the convenience but for the resort itself, WL is a beautiful resort and it has many added benefits as a deluxe resort
Also you can upgrad your ressie since the deadline is June 4th. Even if the deadline is up since you do have reservation I think you still can make the change. I did this last year when free dining was offered.
