Happy Halloween! It'll be that time of year, and there are plenty of pumpkin patches to choose from if you're wanting to do fall activities. There are at least 2-3 in the McKinney/Allen/Frisco area. There is a large one in Arlington if you're okay with the drive (Pumpkin Nights- varying activities, lots of lights).
Bowling, laser tag, arcade games, etc. Great place to take kids! Recommend reserving a lane for bowling because the wait times can be pretty long, especially on the weekends.
Super fun even if you don't like golfing! Decent drinks and appetizers too! Recommend booking a bay(s) online to avoid long wait times.
Plenty of nature areas, parks, and hiking trails in the area as well if you're just wanting to explore.
There are several malls and outlets in the area. The ones closest to the hotels are Allen Outlets and Stonebriar Mall.
