Hi everyone! I love this post because you can't go wrong! I mean, I'll be honest, we always make lemonade out of lemons with any stay and haven't had a bad one yet. But, back to your question -- we happen to LOVE both resorts and just did a BWV/BLT split stay in August without issue. Everything was planned out and worked just great! We did HS, Typhoon Lagoon and Moonlight Magic at EPCOT from BW then transferred to BLT for
MNSSHP at MK and additional nights. While our luggage was being transferred we visit the outlets at Vineyard and Disney Springs then went to BLT for Painting with a View and when we were done the room was ready. We love BW for all of its amenities like walking in the morning near the water, boat transportation, Fantasia Gardens, Beaches and Cream (etc!) But, we love coffee at the Contemporary, going to TOWL about every night we are not at a park, the pools behind the Contemporary and renting a Cabana there, the boat to Geyser Point and the feeling of being in the great outdoors, and taking the monorail to Ohana (etc!) We do love BW and all the resort offers. At BW, we have had Boardwalk views and Garden views and there is a great vibe in the evening on the boardwalk. The bus to Magic Kingdom has never been long for us. We have taken the Minnie Vans and I do love them, I just don't think we'll spend $25 for the three of us again since I have never had a problem with bus transportation. However, they are fun, clean, convenient and just so darn cute. And actually, we use Lyft and Uber quite a bit to/from Disney Springs or the outlets with much success and much cheaper.
I can't sway you either way because whether you go all-in at BW or BLT you can't go wrong and with a little planning, a split stay can offer a little something different, too. We like to mix it up with each stay and add special experiences or dinners and a split stay makes it feel like the vacation is even longer (just in my opinion.) Whatever you choose, have a very magical vacation!
