We do this often. When we have had the grand suite, we have had dinner with 6 guests. Many times I would order appetizers first. We have them with drinks on the balcony. A little later, I'd order the main course. And then a third order for dessert. As someone said, tips are very much appreciated and when you order three times with a large order, I have given nice tips with each order. It makes a very lovely dinner experience. If it is just the two of us, I order everything at the same time.
