MWR Life offers discounts on travel needs services such as flights, hotels, resorts, cruises, vacation rentals, car rentals, excursions, theme parks, and trains.
One has to purchase a suitable membership to join MWR Life as a Guest or an Ambassador. They have to recruit new ambassadors, sell memberships to guests & earn commissions from them.
This decision is up to you, but I will not recommend MWR Life. Nowadays there are several free options available to book any services online in cheap price.
