my school limits the amount of one type of rotation we can do...yours might too, you should check. if you can do unlimited anesthesiology rotations then i would set a few up for late summer/fall at places you think you might want to go. this is prime time for potential candidates to do rotations. take some time off or book easy rotations with cool preceptors that will give you loads of time off for interviews in dec and jan. you can do a sicu rotation if you still feel like working but trust me but senioritis will set in so plan a few cushy, laidback, thinking-optional rotations for the end of fourth year so you can recharge after boards, travel, interviews, etc and be ready to work your ass off as an intern.
