Do they carry very different merchandise from each other?
And does Paradise Pier carry more water/beach/tropical themed stuff?
Do they have "good" stuff or is it more touristy type stuff?
And if you buy one thing from 1 hotel but are staying in a different one, (all on property of course!) will they send it over? (and would they need that 1 day to deliver like I think you'd need if you bought something at the park?)
