You won't be able to do it if it's under his name. Yes, mot things (maybe all things) require the person to have an MLife players card. Not sure if you need one for things like the Shark reef or Secret Gardens. I will find out in January as I will be going to the Shark Reef. As far as I know the only way possible to do it is have all of the vouchers in your name. He might be able to fill out the voucher info with your information though (name andan e-mail). You would of course be doing so at your own risk. As far as I know though MyVegas has no way of knowing or stopping people that use multiple accounts YET. I'll ask Brad to get on here though as he may be explain in better details. Not allowed to have more than one voucher of something per person either. Even with two different accounts MLife can probably flag that since it goes on your players card. I will ask Brad about that too.
