Staying in a hotel or taking a break on a cruise will not lower your Average Daily Theoretical (ADT) for casino offers because casinos look at your entire hotel stay or the full length of your cruise. Your daily play is calculated by taking the total theoretical amount for your trip and dividing it by the number of days you stayed or sailed, so it does not matter how you choose to play each day.
However, if you just drop by a land based casino and only play for a short time, it could lower your average play and affect your future casino offers.
