Also, you can make PSs at your resorts front desk, they are tied into the Dining computer system.
And at OKW, I sometimes have had the "greeter" at Olivia's be able to make a PS in the parks while we enjoy our breakfast, as they are also tied into the Dining computer system. If the front desk CM or restaurant CM aren't busy, this is a good alternative to being on "hold" since the phone system seems really busy these days. Otherwise, guest services in the parks is a good option.
