Yes you can but only if they are rooming with you. If they are not rooming with you then they should make their own reservation. To add another person to your reservation as a roommate, all you need to do is contact us at (575)434-3944 or send us an email to email@bethelcoachtours.com After the person has been added to your room, a BCT agent will correct the price of the remaining travelers on that reservation accordingly. By adding another traveler to your reservation and therefore to your room, that will save some money on the price of your trip. Price-wise the more in the room the better.
