Need help. I am evaluating comparable companies, in the cruise line industry $($Royal Caribbean, Carnival & Norwegian$)$ to assess their liquidity, solvency, ROE, ROA, leasing exposure, and margin analysis in the sector. Need to present a sound analysis looking at these pertinent operational metrics. Also, would it make sense to partner with any of these companies? Would it make sense to invest in any of these three companies? Evaluation over a $5-$year time period $(2018-2023).$
