Can I add standing cocktail tables with no seats?

Yes. The 30-inch cocktail table (60 cm poseur in metric), under Tables, Cocktail tables, is a standing high-top with no seats: guests are not assigned to it and it never counts as seating. Use it for the cocktail hour or the bar area on the same plan.

A cocktail table is placed, moved and resized like a furniture item, so it does not count toward the table limit on the free plan.
