Here is the problem, thinking that if you get a one bedroom and a studio, that it will connect...even at resorts like OKW where ALL one bedroom connect to a studio. Since resorts, unlike cruise ships, do not not completely empty and then bring in guests all at the same time, there is no way to guarantee that the party that may be occupying the studio would leave on the day yo need it.
For instance say there are 2 two bed lock off units at a resort, that are booked are 1 bed and studios Party A wants a one bedroom June 1 to 15, Party B wants a studio June 2 to 17, Party C wants a one bed June 3 to 5, party D want a studio June 4 to 6, and so on and so forth. It is just the way the system works, and problematic that lockoffs booked as one bed and studio would ever match dates exactly, so in your case, getting a one bed and studio, connecting, for the same dates would be very rare,
