I'm a huge fan of the DoubleTree Suites on Hotel Plaza Blvd next to Disney Springs. I've stayed many nights (50+) in the past couple of years and never had more than a minor problem that always get fixed instantly. (Stuff like broken TV remotes or soap/shampoo that didn't get replenished.) Most stays have been blemish-free.
Suites are similar to the Buena Vista Suites: a bedroom with either 1 king bed or 2 queen beds plus a sleeper sofa in the living area. There's also a wet bar with sink, mini refrigerator, and microwave. The DoubleTree rooms are wide, not long like at Buena Vista Suites. By that I mean that the living room and bedroom both have windows.
If you're looking to save money, you can easily walk from the DoubleTree Suites to cheaper off-site dining options like McDonalds, Perkins, and Taco Bell. It's about a 10 minute walk. (If you need a late-night snack or early morning meal, both McDonalds and Perkins have dining rooms open 24/7.)
Transportation is provided to the theme parks every 30 minutes. There are two buses, each visiting two parks. One will usually go to the Transportation and Ticket Center (bus/monorail transfer to Magic Kingdom) and then Disney's Animal Kingdom. The other usually goes to Epcot, then Disney's Hollywood Studios.
I've never priced the Buena Vista Suites, so I can't compare. The DoubleTree Suites rates can be as low as $109 or as high as $200+. Parking is extra but there is not a resort fee.
I always check the Disney Springs Hotels marketing website to see if there are any discounts available. Any links there will send you to the official Hilton website, which means you can earn frequent guest points via the HHonors program. (If you're not a member, be sure to sign up prior to staying. It's free and points don't expire as long as you have a qualifying activity every 12 months.)
