That's a week earlier than usual for the Panama Canal cruise. I doubt I'd book it because it conflicts with other cruises I already have booked. However, if I did go on that cruise - I'd be at WDW on my birthday the day before!FYI I just checked the San Diego port calendar and the Wonder is showing up there on May 7, 12, 14 & 17 of 2017.
If the westbound panama canal cruise is 14 nights, this would have it leaving on April 23 2017, which makes sense since the last posted cruise for the wonder is a 3 night out of Port Canaveral on 4/20/17.
