BarbaraMB- I was also told I'd need 2 ent cards, but at the last minute we only needed one room, and they did ask to see my card. I have seen other posts from people who did not need 2 cards for 2 rooms - but if you have one from a family member or friend I would take it along just in case - they don't take down the # from it or mark it in any way - so I don't think there is any way of knowing if it had been used before or not.
I also received the wine even after being told over the phone that no Loews perks could be given with the entertainment rate - so maybe by the end of Aug they had fixed that.
