COVID testing at Port Miami for side to side cruise?

[Cruisin4beaches]

Sailing on CCL Freedom 3/6/22-3/12/22 then onto RCCL Jewel of the Seas 3/12/22-3/20/22. Is there testing  available I can take between the 2 cruises at Port Miami either at Carnival's terminal or Royal's?

Can I ask Carnival to test me on board for the next cruise?

I realize I'll have to pay but can it be done?

Thanks in advance for any helpful input.

You can ask Carnival.
