We drove for the first time in December. And we loved it!! DS10-said he never wanted to fly again. We drove straight through. We left at 4am and arrived at 8pm. I drove 4 hours. DD16 drove 4 hours and DH drove 7 hours.
I thought I would be really tired at 6am the next morning when we woke up to check in at BC, BUT I was less tired. I think being able to move around in the car and stopping every 4 hours for a potty break really helped. We have 2 portable DVD players that really made the time pass.
Flying really only saves us about 6 hours. When you consider the drive time to the airport, arriving 2 hours early, layover at another airport, getting bags, getting rental car and getting to resort.
We plan on driving for the next few years. I'm sure it will get old after awhile.
