It's all about the lounge for us, and depends on the type of trip/touring and how many people are in the room. For trips that involve all day touring, I wouldn't recommend it (though I wouldn't dissuade someone from booking it, either). In the winter the weather is often lovely and the parks close earlier so, we tend to stay out all day. On our summer trip, we took afternoon breaks and also stayed at the resort during thunderstorms. The lounge was kind of a refuge for us. Additionally, we were 5 with 3 bottomless pits. We get a lot of $ value from the food offerings on family trips.
I only used the concierge to make ADRs our first trip, I believe their duties have changed quite a bit since. I enjoy playing with options so I've done it all after that first trip. Our typical use is breakfast, snacks around pool time, beverages whenever we're at the resort, and apps if we happen to be there instead of at a park.
