Also, you may have noticed from posts that many people have only a few days in Cuba and therefore a tight schedule. Flexibility is not as realistic with just a few days/nights in country.
I have written before about my belief that the "tight schedule, no flexibility" approach easily changes what should have been a great experience into the "been there, done that, it was OK but no desire to return". I talk to many tourists in Cuban airports as we wait for our flights home and see that too often.
E-mail actually works great to talk to casa owners, and the majority answer promptly. The casa owners seem to have leapt into entrepreneurship and all it involves, including even Trip Advisor reviews. LOL So maybe the times they are a- changin'.
True, but it does limit the options available to travelers to a small section of what is available as you still find many more casas that have no internet presence than those who do. It does give rise to the online belief that it is difficult to find accommodations when actually in Cuba one finds many available places.
Personally, I ignore TA reviews as I have read too many reviews of places I know from actual experience and find the reviewer had no real basis for comparison. And far too much emphasis on specifics that were uniquely important to the reviewer but not the majority.
And you do realize that the posters on TA are many of the same regulars here?
And many of us know each other personally, communicating privately, and sometimes getting together for a beer.
TA does have an over abundance of the "OMG, I have actually been to Cuba (once). Can you believe it? Now I must tell the world what Cuba is all about." kind of posters.They have difficulty accepting that Cuba is not Area 51 and they are not unique. Also those whose Cuba experience is narrow and do not understand that others may desire something than they do.
In summary, I just see large differences in the Cuban travel and Cuban culture discussed on the internet and the real world that exists with your feet on Cuban dirt.
Once again, everyone should do what they want. We are all different.
