I’ve traveled cross-country by bus multiple times and learned that prep is everything. One time, I got rerouted without warning and had to contact Greyhound customer service to figure things out mid-journey. It wasn’t ideal, but they helped. Always check schedules beforehand and bring more water and snacks than you think you'll need. A blanket or large scarf is a lifesaver on chilly night rides. If you're social, chats with seatmates can make time fly. If not, a good playlist or audiobook does the trick.
