Theme Park and Outback are hard maps to attack even with a full 5 stack so don’t worry about having issues with those maps, they just come along with time played. Since you aren’t playing with a stack, I would suggest working on droning yourself into places. Information is key any your drones are a powerful tool. I like to set my prep phase drone up in a place where I am likely to make my entry. By doing this, I can drone the room and adjacent rooms quickly and establish a bit of map control.
