We use the website Tripadvisor a lot when traveling. It has info on sites and lodging and reviews by visitors as well. You do have to realize these are other people's views which may differ from yours. A good example was the reviews we read about a Best Western that was a little off the beaten path I guess you could say. It had all great reviews except for one which you could tell was written by someone younger, maybe college age. It complained owner wanted to charge him extra when he brought 2 extra friends (total 4 people) when he had made reservation for 2. He arrived very late, a friend threw a drink in parking lot, they yelled and couldn't believe owner threatened to call police, etc... You probably get the idea. Anyhow, we decided it was probably a good place to stay and quiet because owner didn't put up with any nonsense. It turned out to be a very good choice.
You can also ask questions on the forum and there are some very helpful people out there willing to give their advice. Also search questions already asked and you may just find your answers posted already. When we travel, we all often have similar questions.
