Tourist traps quickly smother the screams of those who suddenly wish they'd gone another way instead. When being shown around the realm, ensure your guide has the proper qualifications and check how long they have been in the job. It the answer to that is a week last Tuesday, be wary. The guide has obviously taken over the routes of someone who fell foul of the traps.
Having said that, the other meaning of the phrase also applies. The major tourist trap is the area around the Palace where people can get good views of the grounds. Many of the Kingdom's villages and towns are very pretty and are welll worth a visit. Just ensure your guide is properly qualified. It builds confidence if they've been in the same job for more than three months!
