No flames, really, just my thoughts on your post:
I was thinking that all of those things were important and worth the extra money to me, so I booked the WL and Contemporary concierge for our Christmas trip. Then we stayed at ASMu on our recent trip, and we all (including DH, DS14 and DD11) loved it SO much.
We had two connecting rooms, so the cost was $154 per night, but we had two TVs, two bathrooms and double the space. We drove to all of the parks and restaurants we wanted to go to, and even drove to get on the monorail when we wanted to. We don't drink, so the bars and lounges didn't mean much to us. I was happy with the shopping choices at ASMu, and there was DTD for serious shopping. My kids don't care about slides in the pools or hot tubs, just the fact that there is a pool, and the ones at ASMU were lovely. We never used our tiny balcony when we stayed at the Poly anyway, and the walkways at ASMu were covered at least.
After considering all of this, we changed our Christmas reservations from one room at WL to 2 rooms at Pop ($59 per night with BRP). Our family will be much happier, since we all need our space, and it will save us $1200!!
That being said, we are still going to "splurge" from December 23-26 with a Tower Concierge room at the Contemporary and hopefully that priceless view, but staying at Pop the 6 nights prior will make that luxury so much more affordable for us!
