Okay, the only way you can be in a two-bedroom unit is if that's what you reserved (or if you're really lucky and get pixie-dusted), so that's not a request.
All OKW units have balconies, even the first floor - although those are technically enclosed (with a railing, just like all the others) patio.
So, really, your only request is "water view". Contact whoever you made the reservation with as advised above. If your reservation is a Disney-arranged upgrade from Pop Century or AKL, for example, you would still contact CRO - the number you used for the original reservation.
