I don't think you really have anything to worry about with Azamara, especially based on your particular plans. If you book a Club Continent suite, you don't pay for specialty restaurants so the price increase doesn't affect you. The beverage package upgrade sounds like a big % increase, but it is really a fairly small $ increase to cover the increased cost of wine and spirits – and you may not need to upgrade anyway depending on how much/what you drink. The balcony furniture people are complaining about is on Onward. AzAmazing Evenings are probably impossible to arrange post-Covid because the land vendors aren't available anymore, but they are still hiring local performers to bring the local culture onboard [and paying them to do two shows, not just one].
There were some people who automatically expected Sycamore to bleed the brand just because they are a hedge fund, but all the evidence I see is that they are pursuing the opposite hedge fund MO: build up the brand [they bought Onward and poured money into renovating it right off the bat] to make a profit by selling it for a high price.
Finally, Azamara's recent marketing now lists not just how many overnights a cruise will spend in port but also how many total hours in port – this may be a dig at Oceania, but it is also a promise that Azamara is not cutting back.
