I have heard of folks doing cruise shops but not through Shadow Shopper. Shadow Shopper is basically a newbie resource. I know of few serious shoppers who have continued beyond the inital trial period. Shops such as cruises, hotels, resorts and spas are generally looking for shoppers who have been doing shops successfully for a fair amount of time. Consider what the cost of a cruise is likely to be and if you were the cruise line (who ultimately will be 'paying' for the cruise both in not being able to sell the space to a paying customer and also paying for the services of the shopping company) would you want shoppers that were not proven performers evaluating the ship and its services?
