All you need is an entertainment card which I ordered on purpose to get our rate. You could call (the only way to check the rate) the Loews number and ask them what the entertainment rate is for your dates. Then if it's a good one you can book but you won't have to show your card until you check in.
Good luck with it. We got 168 per night but that was during a VERY busy time and I've heard of some really nice rates if the time is right.
