My parner Peter and I did the Infinity sailing that same week last year. We loved the ship and had the best weather they had all season. Did not see other family members on this sailing. Pied Piper had ran a group sailing the week before on the Summit, Ininity's sister ship. We did meet a straight couple of the internet that we became good friends with. They cruise all the time and we are planning to sail with them again.
Have a great sailing,
