As an answer to your basic question, the answer is definitely a no. I know people who outright should not stay in luxury hotels, it's just not for them. It's all about your preference and personality, even though I could also say with some certainty that even for those people there are luxury hotels out there that they would absolutely love.

As for your closing question, those types of services kind of sounds like a good fit for a luxury hotel in my ears. Cooking classes can often be arranged at luxury hotels themselves, and if they can't concierge should have no problem helping you with arranging it elsewhere. The same goes for the other things you mention. I have no suggestions for you in regards to specific hotels, there are other here who would be better qualified for that, but in essence I would say we are looking at the age old question "What defines a luxury hotel?".
