I also did it twice, once at 5 months, once at 7.5 months. I survived both trips. I took it easy, enjoyed myself and drank a ton of water. I also took many swimming pool breaks, and spent 20 or so minutes in the tub when we came back to the room in the evening. We had a wonderful time both trips, they were during the food and wine festival, so the many small meal/snacks were great for what I could eat. I also wore SeaBands, as I had some motion sickness and "smell" sickness and the SeaBands kept me from being ill.
