How do we accomplish this?

The Short Explanation: All of our vendors got together (Worldwide) and combined their free/unbooked space into a Coastal Lifetime Discount Travel Membership. (Pay their taxes only).

Details ~ 

Each year our vendors are rewarded promotional space on cruise ships, hotel rooms,  and in resorts. In effect, what the promotional space does is help the cruise lines, hotels and resorts reach 85% occupancy because they know that when they do they will most likely be able to fill the remaining 15% at the retail rate.

Let's use
Carnival cruise line
for example.
The cruises that we offer from them in our packages are 4 days and 3 nights...what they consider "starter cruises." The Cruise line knows that even though your room and board, food and entertainment are all provided for, you will spend your money on other areas on the ship like alcoholic drinks by the pool, gambling in the casinos, and shopping in their duty free stores. But the biggest thing for them is their hope that you will walk away with a phenomenal experience on their ship and will share it with everyone you know, therefore branding their name. They also know that you will most likely choose their cruise line again since we usually stick to what we know and are comfortable with.

Lets also look
at a hotel chain
like Ramada.
It costs a standard hotel $11 a night for a room when it is empty. They would rather have you come in and pay taxes...which are $8-$12 a night and cover that cost for them than to allow it to just sit empty. They also know that you will most likely eat at their restaurants inside the hotel or order room service. Most importantly to them you will be a repeat client if you have a wonderful stay.
