I called after I read this post and by then member services (I am a DVC member) was closed. They won't re-open until Monday and by then the increase to the annual pass will be $19 or so. I talked to WDW and they confirmed the increase on Sunday and were unable to sell me the renewal because it was a DVC price.
Oh well...at least I bought my husband and son's pass recently. I was holding out on mine because my anniversary date is after we go to WDW in September. They did tell me it is possible to purchase the renewal before the anniversary date (without changing the anniversary date).
