We are doing a RTW trip that includes two 5+ night stays in Marriott properties in London and Melbourne. Each one has my request for a portable crib/pack n play for the room but neither one will commit to actually having it available. Has anyone run in to a hotel not having a crib when requested? With a 6 month old, it's not really an option to not have one so if there is low % that we will have one then we'd have to take one with us (which would be a big pain).
