Book a flight and/or a hotel.this is important,because sometimes those two can ruin an entire vacation.if you've had a bad experience with a certain airline,don't make the same mistake again.As for the flight,don't let any of it get to you.if it's a really bad experience, you can just say that it's technically not a part of the vacation.Find a good hotel that isn't too expensive and is something unbearable,then let it slide
