As I understand it. the policy is vacation is only allowed during certain rotations. (I think this has to do with needing to do so many weeks in the ICU, for example, to fulfill the RRC requirements. It may also have to do with what rotations function better short a resident like clinic vs ICU.) I wouldnt be surprised if you couldnt take vacation around turn-over. But I dont think they would exclude all of May and June especially since my vacations can only fall in four of 12 blocks.
