No, Ponzi, we were NOT <ahem> too busy 
Hubby was stationed in Germany in the Army. We decided to get married before he got shipped back home. So, MIL came over from the US for the wedding. This was in 1970. So of course, this was a long and expensive trip for MIL to make just for the wedding, and we couldn't just send her back or dump her with my parents.
So the decision was made she would go on our honeymoon with us.
We drove to Amsterdam, Brussels and then Paris. Notre Dame and the Seine and artists and Champs Elysee and such. We tried to see the Louvre, but it was Tuesday and it was closed. I could have sworn it was in a department store right next to it and we walked all around in it (give me a break, I was 18!). Anyway, the Louvre was closed that day.
We tried to go to dinner. Got seated in a restaurant, but my stomach at the time was such that I couldn't eat a thing. Hubby and MIL tried to order, but since I didn't want anything, we were asked to leave, because they had lots of people waiting for tables. Not a pleasant experience! We bought bread and wine that night instead. Anyway, we looked around, but never found the Eiffel tower, and really, my nerves were done by then.
Drove back home, picked up my mom and went on the second leg of the honeymoon with BOTH mothers! That went much better, they kept each other company, my mom with broken English and his mom with no German, but much better. We went down to Bavaria and saw castles, Neu Schwanstein and others.
So that's the story. Two MIL's really on the honeymoon.
PS: If you want a real thrill ride, try driving in Paris, especially the round-abouts!
Oh no...I always thought I had a horrible honeymoon story but I think that beat me.
My Ex-Husband and I were living in South Dakota and were getting married in Maine (at my Mom's house). We flew into NY and then made our way up to ME. His Aunt flew in for the wedding from Chile and we met her on the way to ME. She was very vague about how long she would be in the country.
The Wedding week went great and I was getting ready to go back to South Dakota the day after the wedding and I thought she was going back to Chile but my Ex announced that she was going to come back with us to South Dakota. We were flying out of NY and she would follow behind us taking the bus.
We weren't going to have a real honeymoon until November (this was June) and I had viewed our overnight in NYC as a mini-honeymoon that I had really been looking forward to. We had a great afternoon seeing the sights and having a great meal.
It went great until about midnight when his Aunt called him hysterical on the phone that she had missed her connection in NYC and didn't know what to do. She only spoke Spanish and claimed that she couldn't find anyone to talk to (highely unlikely in NYC). We had to go get her at the train station in the middle of the night.
By the time we found her she refused to ride the bus alone and my Ex and she decided that he would take the bus back with her the rest of the way while I flew back.
I spent that night sleeping in my honeymoon bed with his Aunt while he slept on the floor. To say I was miserable was putting it lightly. When I flew out that morning I didn't see them again for another 3 days.
The icing on the cake is that our laptop was stolen on the bus ride when my Ex had taken a nap on the bus.
