Right, which I am but like mentioned signing up now for it doesn't benefit you any really for the current registration cycle.
While Silver level membership isn't sold out, It won't get you the benefit of early registration for the 2027 race year. You'll have to wait until general registration opens later this year for Club rD or pay the $289 now to join as a Silver member and hope you can upgrade when the opportunity opens for current Silver members, which still won't give you early registration for 2027 races.
I'd just be on all my devices at 9:45 AM the day general registration for 2027 Princess opens. If it is sold out before you pay, try one of the charities. Oh, and don't purchase any merchandise offered for pre-sale during your registration process until you've paid for the registration and received confirmation. You can always go back at buy it.
