What’s your travel style: serendipity or advance planning?

Planner. We’ve done Disney about 10 times and planning is a must but it’s fun and easy for me. And for other kinds of trips I like to have enough ideas to pick from and not just be discussing what do we want to do and what even is there to do around here. And we don’t go on vacations to lay around the hotel. DH used to romanticize the idea of showing up at a hotel and perusing the brochures in the lobby to decide what to do but now he appreciates how fun and smooth our trips are. And we can still browse the brochures and modify plans but I at least want to have enough ideas in advance to fill the trip if we don’t come up with anything else.
