I have no truck with the OP, but in my life and line of work, words do tend to have a precise meaning, as I know when I get it wrong myself! The OP initially stated that their friend wanted to see 'the ocean'. I just wanted to note that the sea being mentioned wasn't 'ocean'.

I think there is a small technical difference between sea and ocean, from a geological perspective, so much so, that the 'Caspian Sea', the world's largest inland body of water, is actually, technically an ocean. Who knows, maybe OP's friend was a geologist and it mattered?

Anyway, OP has clarified the position -- their friend wants to see a large body of non-inland water, presumably with waves and tide (although even freshwater lakes can have those) and a whiff of 'sea air'. I hope the recommended area fulfils the necessary tick-boxes.

To be fair, I did headline my post as 'pedant alert', since I suspected there was a substantial probability that 'sea' and 'ocean' were being used inter-changeably.
