In 2024 we did a big family trip with 5 adults and our one granddaughter - we booked at BLT, had a two-bedroom and a studio. Our single son stayed in the studio, and husband/me stayed in the 2 BR with our daughter, her husband and our granddaughter. It worked out perfectly, especially because we knew our granddaughter (just 2.5 yrs at the time) would need to rest in the afternoon, and get to bed for the night earlier than the adults.
The 2 BR had one king bed room and one 2-queen room; each bedroom had a full bathroom and their was a third full bathroom (presumably for anyone who slept on the sofa-bed in the living room). Full kitchen, and we splurged more for a theme park view. It was WONDERFUL watching the MK fireworks at night from our room, with the music playing in the background on the resort TV channel.
Yes - it was pricey...but worth it for this special trip.
