Travel through the city at different points should include "Elevators" of pure air that lift residents up and down.
Maybe a river that defies Gravity and is used with Boats to travel the city.
An Aquarium that doesn't need to stay behind glass? its like a city Park in a normal material plane city and people can enter and walk around within it. Perhaps if they cant breath under water they can pay for apparatus or a Spell to be able to go in? From like a vendor?
Races through a desert landscape quarter where they race sand ships for sport in an Enormous "arena" area?
Gladiatorial Style games where people fight Elemental style battles ( Magical or otherwise)
The Arena Magically keeps the most destructive magic from spilling into the city or to the Spectators?
..huge libraries
..elaborate bathhouses
..magnificent city gardens: rare plants and elemental/magic sculptures.
..open-air amphitheater: strange wind instruments
..maybe some type of aerial races
Some kind of race seems really apropos, I totally agree. I'd been thinking of saluqi (desert hound) races, wherein participants can either bet on their own hounds or polymorph into hounds to race... but I like the idea of a wondrous aerial steeplechase through the city... IIRC the City of Brass has something similar (and the PCs in this game are likely to visit the City of Brass), so I'll have to come up with a way to differentiate it.
I also was thinking of bathhouses, libraries, hanging (maybe floating) gardens, amphitheaters, and animal menageries / aquariums.
I also really like the idea of "air elevators"! Maybe that's how non-jann who can't fly on their own get around the city?
