Near Hospitality House is now a guaranteed booking category at OKW, and needs to be booked at the time of reservation. The buildings in that category include 11 to 14 and 23 to 26.
Your next best solution would be to request Bldgs 62 to 64. But that is a request only, and not guaranteed.
Remember that no buildings, except 62 to 64 have elevators, with a heart condition, I hope you requested first floor or elevator for medical reasons. Wouldn't not climbing stairs be a higher priority for you? Also, for a heart condition that limits mobility/walking renting a
scooter for your trip would probably be a good idea, as there is also a LOT of walking in the parks. That way you could have the scooter for use around the resort, as well as the parks, and location within the resort wouldn't matter as much.
For scooter rental contacts, look on the disABILITIES board for a list of companies in the FAQ threads at the top of the forum.
Also remember that if swimming is part of you recommended therapy that OKW has 4 pools, the main pool in addition to 3 neighbood pool thoughout the resort. All are nice pools.

disABILITIES! FAQ. Post number 2 has links and contact info for scooter (
ECV) rentals.
