My advice is to do your research. Often, if you take a walking tour or food tour the first day of your trip, then your guide will let you know what are the don’t miss places and possible discounts. Don’t overlook weekday visits, which are usually cheaper. Read expiration dates and exclusions. It is good to plan ahead, but make sure your discount, or Groupon is still good for when you go. Do you have a Restaurant.com certificate? Read it carefully for details. Some aren’t honored on holidays, weekends, etc. I highlight this information in yellow.
Even though this blog is about the attraction card, avoid visiting places during prime season if you want reasonable accommodations. There are gorgeous places to rent in NOLA through AirBNB or VRBO at minimum prices, but not during Mardi Gras or Jazzfest. Same goes for Salem in October.
