What you need to remember is that the bus tours operate at scheduled times which means you need to be ready for pick up at given times. Apart from arriving on time to pick you up a good company could offer to come right to your accommodation facility to pick you up rather than creating a terminal for everyone. Determine what works best for your convenience when choosing among the tours. Drop-offs should be just as suitable.
On board snacks and drinks
Some tours can be quite long depending on the areas they are designed to cover in a day. Because you may not have the luxury to keep stopping to snack or eat because of the time schedules, it is important to consider what is offered on board so you can pack anything else as you deem fit. Some companies offer complimentary morning snacks, sandwiches and even water at no extra cost. The more you know the better prepared you will be for your day tour.
When it comes to bus tours, you are likely to stop at some sights and check others out from the bus. Find out about the sights you will be visiting and exactly at which ones you will be stopping for a little exploration and photo takes. This is important especially if you have target sights that you feel are a must visit during the tour. In case your favorite sights are not scheduled for a stop, you can make special requests if possible or choose a different itinerary that covers your preferred areas.
Experienced local guides make some of the best. This is because they are familiar with the localities and providing you with all information, stories and even interesting facts about the different spots comes easy. Also important to check is whether they are salaried or they rely on tips and commissions they get on the bus tour. Salaried guides are happier and interesting compared to commission based guides who might be more interested in taking you top optional sights at a fee.
