I don't think it'll be that big of an issue once the entirety of the new bus loop is open and then it's just select hotels and ride share (& Mears) pickup/drop off in that area. Most of the buses that currently ran in the former charter stations were only busy for pickup at night. August will be rough with ALL hotels using that area, but once that period is passed, it should be fine.
Still, providing no shade is just dumb. I expect we'll see umbrellas go up along that route before long.
