Instead of scraping, perhaps you should look into publicly available data to the free for anyone to use. As you can well imagine, the places you are interested in (hotels, bars...) generally want as many people as possible to know about them.
Many places will have a chamber of commerce or tourist board whose job it is to attract people to their area. You can call these people and ask if they have a list of members, tell them what you want to do, and ask what restrictions, if any, there are on the use of their data. Since your interests (making the public aware of these businesses) closely align with theirs, they might be quite interested in helping you.
You can also have a page on your website where a business can provide you with their information. Obviously if the business provides the information themselves there is no legal issue.
Finally you can email businesses to encourage them to visit your website and provide their business details.
