I'm pretty sure that you can hop forward three times in a row. Last year I had to sit on a flex restricted week until I could use it. It was expiring in either late November or early Dec. On Aug 21 I booked an Oct week at Shadow Ridge. The next day I decided to add eplus and book a December week at Ko Olina instead (studio). Then in September, I eplussed into Kauai Beach Club but the dates were a bit off. I did my final eplus back in to Ko Olina (1 bedroom) on September 25th. I am also pretty sure that the originating week was a replacement week to which I was able to add eplus.
