If you look at VWL which got the same refurb you can book 9 adults plus 1 under 3 in either dedicated or lockoff 2BR's. Nothing changed to 10 over the age of 3. I'd assume that BCV will be the same. So the dedicated 2BR would still just have sleeping space for 8 and you would have to bring bedding for the 9th but the lockoffs would have the extra murphy bed so you wouldn't need to bring bedding for the 9th. Interesting lthough for VWL - the
DVC booking website still doesn't indicate the murphy bed in the lock-off and says you'll need to provide bedding for the 9th. It has been updated to note the murphy bed for the studio though.
Was one under 3? That's the only way I can get BLT to accept 10 total.
