When hubby and I are sailing alone, without friends, we don’t have a problem doing SD without reservations. We enjoy sitting at a table with new people every night. It gives us a chance to interact and talk with new people from different walks of life. What a good learning experience. Plus, not knowing what our day will bring and having to possibly rush to get to our “reserved” time after possibly having a busy day. Plus, there are times where we may not be too interested in either getting dressed for dining room etiquette or possibly not too keen on what they’re serving that evening. You’re on vacation. Go with the flow I always say.
