Is there an area on the premises that I canbring your own bbq to make a few bergers and dogs?? If not what’s the closest place

There's no place on premises that you can set up a grill, no.

No!

Not to answer a question with a question but I am so curious to ask the inquirer, have you been to any hotel of this class and was allowed to bring your grill with you? This is not a motel. I believe that their insurance policies would not even allow any sort of picnic/jamboree on their premises. They have about three restaurants on this premises that serve burgers and dogs so I would avoid bringing grill to this high end hotel.

That is an unusual request. I recommend contacting the front desk. The Sheraton is a high end hotel...probably a 4 star or 5 star hotel.

I did not see any space where it would make sense to bring and setup a grill. The location is near the harbor across from the convention center. Down the street from the baseball stadium. Maybe there is a park near the stadium.
