Does it matter if I play on oneor two days?

I will be staying at Aria for 5 nights in June and decided to fly out the night before so I will have 5 full days there.
I was going to stay at a property I have never tried before to check out something new.
Then I got an offer for $750 free casino play from CETthat requires a 2 night stay.
I am going to take advantage of it and just leave on the second day.
My question is does it matter if I do all my playing on the morning I leave or play some when I get there at night and some the night before.
I have not stayed at a CET property in Las Vegas in 3 years but I am still Diamond from several Atlantic City trips a year and don't want to totally screw up my ratings.

You will get multiple answers on this one. Years ago, when we could actually see our ADT, we knew that only playing one day, and NOT using your card the second day would result in a higher ADT. Hosts would always say differently. What happens these days, who knows.

Personally, I would go ahead and take the offer, assuming you will be playing a fair amount at a single CET casino. It does not matter if you stay in the room or not. The day you actually checkin will count as a day with CET for sure. 2nd day? Nobody seems to know.

More than once we have taken a free room from CET to use an offer, but never stayed in the actual room.

The first time I stayed at Ceasar's at the invitation of my former Venetian host. I was offered $1000 free play and rooms. I stayed two nights but only played heavy one day. The offers have continued since then. So in my experience, one day's action even if your stay two nights for the offer, will work out.

In the above situation, one of at least two different things happened, and we do not know for sure which one.

a) You stayed two days, played heavy one day, they averaged your play over two days and liked it, so they continued to send offers.

or

b) You stayed two days, played heavy one day, but they only used one day for your average play, liked it, so they continued to send offers.

How would anyone know which one of these scenarios is correct?

Rule used to be...in CET's eyes, a normal stay was 3 nights and that's what they looked at for your ADT level. Play the 4th day and ya screw it up.
DON'T PLAY FOR POINTS/LEVELS...PLAY FOR ENTERTAINMENT. It's nuts to spend lots of money to get
something for ?free?.

Greg I agree with you 100%.
Since I'm going to actually be there only one night of the reuired two I was just wondering if it made a difference if I confined my play to Tues.night or Wed.morning.
I will be playing the same amount total either way.

Since you are going to be playing the same amount total either way I would go with concentrating all the play on one day.
If the CET system looks at ADT based on the actual days of play this will help. If they look at it based on the number of days you stayed it will be the same either way. Therefore go with the choice that might help.
