I'll let passes lapse though and then go about six months before buying again. Then we'll bunch three trips out of the next ones. That's not bad for being 1000 miles away!
Normally get MYW no expiry. But now with AP discount I bought 1 AP for the AP discounts on AKL prior to DVC trip, and DDE card. Rest of our party of 16 is either using previously purchased MYW no expiry, or recently bought MYW expiry depending on logical future travels.
