During the meeting, you should ask the agency representative about the kind of services they offer, and you should also ask about the prices. You should also inquire about the agency's cancellation policy, so that you will not be charged if you decide to cancel the booking.
Once you have decided to hire an agency, you should make sure that you understand all the terms and conditions that are involved. For instance, you should find out how long the booking will last, and you should also inquire about the agency's refund policy.
