I just returned from a visit to Coronado Springs Business Class. All in all it was worth the money to me, $20 extra per night for me. Now I did ask at check if I my key would work in the business lounge and they had not set it up right, so it took a few managers and about 20 minutes to get it figured out. I'm glad I asked and didn't have to return later. The check in desk is just not used to the Business Class yet I guess.
I was there for a conference, so I didn't always go in the morning for breakfast, since breakfast was included with my conference, but I did visit a few times and enjoyed the fruit and cereal. I went almost every night for snacks and drinks and that was fun. One night my daughter and I spent a few hours in there, filling out some paperwork, drinking and chatting with the concierge staff.
I did not find a self serve refill station at the Dig Site, but the bar filled up the mugs. Maybe it was there and I just didn't find it?
This was my first time at Coronado, I really liked it, I usually stay in
DVC properties, so I wondered it I would miss anything. I did miss a microwave, I might have been able to request it though.
And I missed having a table. I just don't use a desk much, I usually work from bed when on a trip!
I used the robe!
I jogged around the lake a few times a day, so once you do that, the property doesn't seem so large.
I'd be happy to answer specific questions.
