Perhaps I should explain. My May 2023 Black Sea Cruise is the linchpin of a 2 1/2 month trip beginning in Japan, ending in Greece, and including 4 cruises, 2 flights, several hotels, a train trip and multiple excursions. These things take planning and are not easily (or cheaply) put together at the last minute. Anyway, we're already almost half-way through 2022. 2023 is not that far away.
