Thanks OTC I appreciate the advice. I'll let her know.TBH MEB_ I don't think the area is overly wheelchair friendly if you had to traverse mounts bay road footpaths. It's no doubt expensive at the adina but probably the best for accessing the convention centre. I think a better option would be staying a short distance and cabbing It for accessibility purposes but Perth has an awful reputation for people waiting for disability taxis.
As for the second part I wouldn't have a clue other than the zoo which is on the other side of the river
