Easy, go thinking with your big head, check services and extras politely but in detail both by text before you travel and in the room before you hand over the cash, and be ready to walk if the story changes. Be particularly wary of fabulous looks and evasive answers. Don't travel a long way and have a next day back-up if you have to walk. I'll punt anything I fancy in my local areas because it is so easy to plan b.
