We went in July and decided to pass on rental car this time and booked the 4 days pass with the Waikiki Trolley and we love it! We went on all 3 lines and had a great time on the ride. Our drivers were informative and quite funny - Bill on the red line, Keoki and Sisso on the blue line had us all laughing the whole time. I wish the trolley would go to Kailua, that would be a fun stop, hopefully in the future. One thing I would love to have is having 2 trolleys at the first stop on the blue line. We were up early for the 8:30am pick up at the 1st spot and yet the trolley get fill up fast and we all had to stand, making it hard having children with us. Overall, great experience
