No offense but when you posted how you planned to get all of the current zones' game overs finished by april I thought it was a pipe dream going by your previous update rates. But you sure proved me wrong. Way to go!
If you do decide to continue GO's in the next update, whether after your vacation or not if it is cancelled, I would recommend just doing the holiday enemies' GO's and setting aside the tomb GO's until you start working on the tomb proper.
