Ferry vs Tunnel

With our daughter here from the States, we decided to take a small vacation to England. My husband had been there before with the wrestling team, but hadn't gotten to do any sight seeing. We were told that for the first time, to take the ferry from Calais or Dunkirk, France up to Dover so we could see the White Cliffs of Dover, then take the Eurotunnel home.
Once the ferry takes off, it's about 90 minutes from coast to coast. You follow the signs to the right place and go through the passport stops for England and France then queue up and wait in line to drive up on the huge ferry boat. Easy enough. I believe the ferry had 3 floors to park on, and 3 more floors to shop, eat and relax. Pretty sweet set-up. The shop is a duty-free shop, so there were some good deals there, if you wanted to pay English pounds and suffer the exchange rate.
There was a small kids area with a video playing and some tables with games that were bolted to the floor.  A couple of coffee shops and a cafe to purchase snacks, or you can bring your own. Wall to wall windows to so you could look out and see the scenery, in this case, the cliffs bobbing up and down with the waves in the torrential downpour.
The ferry was nice, and about $30 cheaper than the tunnel, but with the weather that we were having, all the movement of the ferry through the waves was making me wish I had brought sea sickness patch or something. The kids were fine, but the husband and I were a bit queasy.
We took the tunnel on the way back. This, to me, is an amazing piece of technology and engineering, a giant tunnel, big enough for a double decker train to drive under the English Channel. (I was kinda geeking out about it, which I don't usually do) The only thing that could have made this cooler is if part of it were in plexiglass so you could have seen the water. There were several locations to see a departure board that told you when your train was queuing up and loading, and with 2 trains every hour, it was very easy to catch a different train if you wanted to leave earlier or later.
From the time we queued up, to the time we were on the train was 20 minutes and from the time we drove on the train until we got to the France side was 40 minutes. It took only 25 minutes of drive time. 25 minutes and the train was not bobbing up and down, it was smooth riding. I'm not a claustrophobic person, but even if I was, I think it would have been ok. You ride in your own car on the train, you can get off, but other than a restroom, there really isn't anywhere to go. We just stayed in the car and read our books.
While the tunnel is more expensive, it is worth the money to me. The queues are shorter because there are so many departure times, the trip is an hour quicker and you don't have to worry about barfing because the beautiful cliffs are moving up and down on the horizon.
