How quick are share certificates issued

Hi
I’m looking at buying carnival shares to take advantage of their free on board credits. How long after purchasing shares is the share certificate issued. It’s just that I have pending cruises. Thanks

They should just accept the monthly statement as that has all the information that they require.

Most shares are typically held electronically nowadays

You need 100 shares.

From what I recall share certs are dispatched on the date of settlement iirc.
