The survey is a random survey Virgin sends out to customers.Not something you can request.It is not the same as the survey sent out after a cruise,surveying service.
The rules lisabucsfan1 listed are the rules you receive with the access code to be used when you book a new cruuise,in order to get your obc for taking the survey.Yessss.I have reached out to Virgin and expressed my concerns and am waiting for a response.
