There are always ship locks in event, but depends on what difficulty you are going for. Easy mode usually does not have Ship-lock while Medium and Hard does. It is recommended to wait few days before storming an event map. Just take a look through the rewards, ship drops and stuffs. If you think you have enough ships to handle Medium / Hard mode due to nice reward, go for it, else its your choice to go for Easy.
