I still am not sure where you are staying but since you are requesting first floor and hospitality house location, I assume it is at OKW?? A lot of people prefer a dedicated 2 bedroom with children because in a 2 bedroom lock off you have a door in the 2nd bedroom which opens to the outside of the unit. Other people prefer them because, at OKW at least, you have more closet space in the 2nd bedroom in a dedicated unit. Unless your child is young and will be in the 2nd room alone then I personally don't see how it would be an issue whether you got a dedicated 2 bedroom or a lock-off. I will say in 10 years of OKW vacations, every one of them in a 2 bedroom, we have never been assigned a lock off except once, and that was when we requested it specifically. OKW is unique in that they have a large amount of dedicated 2 bedrooms. I really think it would be pretty unusual for you to get a lock off unless you requested it there. Remember to list your preferences in order of importance. Requesting a general area is better than requesting a certain building which is what it sounds like you plan to do.
