My family and I are heading to Boardwalk in April only for one night and then moving to the Poly. My husband and daughter wanted to walk to HS and then they plan on hopping to MK. My son and I are staying back. We plan on using Bell Services for our luggage (we won't have a car) and we plan on walking over to HS either to take a bus to MK and walk over to Poly or just take the resort bus back to Poly. My questions are 1.) Will MK busses be so packed that I just take the Poly Resort bus? 2.) Am I able to carry on the bus a very small piece of luggage (think carry on but hard case) on the bus to the resort/park with me.
