Detailed Instructions: Given a travel related situation, and given a specific question about the situation, summarize the question into a title
Problem:My fiancee and I are planning a wedding in South America, and we'd like to make it as attractive and hassle-free as possible for our American guests to attend. To get them excited about the wedding, we'd like to offer guests some kind of travel package that includes:

flight to wedding destination
hotel at wedding destination
flight to resort destination
hotel for resort destination
flight back home

Ideally, guests could just pay one lump sum of money and not worry about any of the booking details themselves. In the interest of cost, I've heard that some hotels/airlines can take group bookings at cheaper rates, but I have no idea how this stuff works. Is creating a package like this reasonable? Is this something that we have to take care of ourselves, or are there services out there than can help us out with this?

Solution:
How do I create all-inclusive travel packages for a wedding?
