Be aware, the process of paying those Interval dues is not without issues. I have had multiple II reps tell me my membership fee needed to be paid before they could help me. I paid it once only to have to try to get a refund from Vistana, which I did after a lot of work. I had a stay in Sedona booked last year that I cancelled 6 months ahead of the stay. I bought the E-plus so no problem, right? No,I got an email with my stay confirmation a few weeks before the dates. I called II and the person told me because I was overdue on my membership fee, the cancellation did not go through months earlier. He said I had to use the stay or lose it. Several phone calls later, I got a woman who told me "that person is new and doesn't know what they are talking about." Are you freaking kidding me? Fortunately, she got me booked for a trip a year out at some random place, so now I can trade into something else. I have owned since 2014 and the level of service has declined every year since, even more so when Marriot took over.
