I remember having the hardest time looking for cheap umbrella strollers in Honolulu of all places. I wanted to leave one with my parents, but didn't find any. Ended up just gate checking our stroller most of our visits.
Walmarts probably your best bet. It's probably a 20 minute walk from the Hilton.
