How much does Cypriot Greek deviate from the standard for a first-time visitor?

I’m taking a trip to Paphos next month, and I’ve been studying Standard Greek for six months, but my language partner mentioned that the Cypriot dialect is significantly different. Should I worry about being misunderstood if I stick to the standard grammar and vocabulary I’ve learned, or are there specific regional phrases I should prioritize to avoid looking like a lost tourist?
