Seeing the Grand Canyon doesn't need to break the bank. If you wish to go on a bus tour, it's actually quite affordable. From Vegas, for example, trips to the South Rim can range anywhere from $80 to $180 per person. Is there a reason behind such a price disparity? No. It all is based on where you purchase online.

Vegas is home to a number of top quality tour bus operators. For the most part, the experience is the same. Buses are modern. Drivers are courteous and well-informed. The on-board meals are good. The Grand Canyon... that goes without saying.

It all really comes down to price. How come some agents sell you a trip for $180? Because they can. As strange as it may seem, a lot of people buy at that rate. Do not be one of them. Shop around.

To help you get the best all-inclusive package, here are several things you need to consider:

1. Is there a fuel charge? It is a "hidden" cost that was added on when the price of oil surged earlier this year. Fuel costs have since dropped. You'd think the charge would be dropped. Think again.

2. Is there a fee to get in Grand Canyon National Park? Believe it or not, some operators will add this expense into the price of your trip, either upfront or at the park!

3. Is there a terminal check-in fee? This is a surcharge for checking into a terminal where you board your coach. This is a warning sign. The good tours pick you up and drop you off from your hotel totally free.

4. What is the trip cancellation charge? You have to really hunt down tour brokers and operators who are not going to hit you with this one. Nevertheless they exist. The rule of thumb is always to ask. If they do, consider your next selection, time permitting, of course.

5. Is there an extra price for meals? Expect to get a pre-packed breakfast and lunch. That's the norm.

6. How long will the bus stop at the South Rim? The National Park is 277 miles long and 18 miles across. A couple of hours off bus is inadequate to take in the Seventh Wonder of the World. In this instance, the more the better.

There are a ton of tour bus operators in Las Vegas. Take your time. Shop around. But bear in mind this one key suggestion: The best specials are always offered not by agents but by tour providers (or tour suppliers as they are known in the business).

Tour operators are the businesses that own the coaches, pay the drivers, offer customer service, and make sure you get the trip you bought. They have a vested interest in making certain you are satisfied. Brokers, on the other hand, will offer you a tour at whatever price they believe you'll pay, which is always more than the tour operator's price.

The Grand Canyon is a "must-do" once you visit Vegas. Especially the South Rim, the part of the National Park that's world-famous for its scenery. Bus excursions are one of the most cost-effective way to visit this rim. But do your homework. Pricing is all over the map. My recommendation is to start by shopping travel company internet sites as in all likelihood they will have the cheapest prices. Then climb onboard your deluxe luxury bus and prepare yourself for the Canyon.
