I always do online check in but always stop at front desk anyway. Always.
SO many times, I get to our room (at BWV, usually a zillion miles away) and nothing opens up the door and have to walk back to the lobby. Now, we ALWAYS have Bands checked. (I never use iPhone to open doors).
Plus, I sometimes I use 2 different memberships or even maybe a renter's membership and want them to know & put in a note that the reservation is continuous (if same configuration of room). It has helped tremendously not to change rooms. Still have to go to lobby on the (new) reservation day but always could stay in the same room.
