Should you keep one campaign running all the time?

No, a campaign that never switches off is unnecessary. Yes, one can stay that asks for a table with the photo of the dish you serve now, reviewed every week and switched off when there is no room left. See whether the photo on the ad that is on is today’s dish. The ad has been running for months and shows a menu that is no longer on. The booking campaign, the date of the last review and when it is switched off.
