Then I saw the tram so I asked them as well. The lady selling the tickets said she wasn't sure, so I asked the driver and they said no problem...so he got to ride the tram too!
Jackson fell asleep on the tram ride and then started to overheat, even though I thought the ride was cool and comfy. So we did not stay too long, he is feeling much better now. We are members though, so we can go back whenever we want...probably wait for a cooler day and bring the wheelchair umbrella. I was very impressed with all the accessibility though!
