I do believe it would be a shorter walk for the bride if staying at the BC to go thru there and walk over to SBP.... I think it is a longer walk from the BWI ... plus going thru BWI you are on a Boardwalk if wearing heels this can be difficult walking, and if my memory services me right going from the BC you are not walking on the Boards, however they may have a secret passage way thru the BWI that may bring you out close to the SBP.
