For us, the drink refill stations are a non issue. I bring all our drinks with us, we don't do the dining plan so we never get the refill mug. For our family, it isn't a good deal to buy one.
We are using Tables in Wonderland this trip (there are 6 of us considered all adults) one of the girls eats mostly salad, and the other two cant finish a meal alone so they may share. But we will be buying mugs for everyone, for convenience, and for something to take home.
It use to be an issue for us at the BWV, BCV with the no quick service. But, the BW bakery is being refurbed & I've read will have a more extensive menu & seating. The BCV rectified the QS issue with implementing it into the gift shop. When we stay at Kidani, at the pool we either get sandwiches at the pool bar or order "room service" pool side. (or bring premade sandwiches from our room) You easily order at the bar area & there is an extensive menu. SSR has added food at the pool in the Paddock section recently too. This tells me that members did have an issue & they rectified it. The only place I don't care for the QS food area is OKW. One of them I've still never seen even after staying there lol & the other is outside & doesn't offer anything too exciting. Haven't stayed at BLT yet but how hard can it be to go over to the CR for QS? And doesn't the pool area have a refill station?The quick service wasn't that hard to get to and that was only once a day, for the days we were at the hotel. But it would be nice to have a quick service closer. The refill station takes many more trips per day, especially with kids ( they don't pace themselves lol). As far as a refill station at the pool No Idea, when we were there the area that looked like it may serve drinks was closed when we were in the pools both early and late on more than one day. Maybe they do but it is not advertised.
FYI, the refill drink station at AKV Kidani pool area is always swamped with bees. (this has been my experience on our summer trips) I'd refill my mugs in the gift shop.
