I was there for robodojo antweight and beetleweight minimeet and honestly it was really well done only one person opening and closing the doors for the arena and cleaning the area doors and top area after every round gloves had to be worn if using someone else robot for a fight if it was the same persons robot vs each other.

Masks had to be worn (you could take that off if you went to your car or standing near the parking area, 2 meters apart but 1 meter is probably ok at this point in time though due to super markets and other places tend to be that close but that does depend on the area.

You had to bring your own toiletries and take your rubbish with you when the meet was over.

Overall it was a really good and relaxed event everyone kept to the social distant rules but like james said you might want to look at the rules for hotels & attractions.
