I went to Austria for my honeymoon, but that was 10 years ago when things were much cheaper! It also helped that my husband had been there a few times before because he knew his way around a little bit: we didn't have the stress of wondering if we were going to get lost lol. Although one day I think we did a little...ended up walking REALLY far and it took a long time to get back....I think that was the Vienna woods we got lost in. It was romantic, but me feet hurt. My nylons were shot lol.
Paris sounds soooo romantic! I want to go there too someday. Did you think of staying in the states or you really want to fly over the water somewhere? I think if I had the chance to go somewhere without the kids on a second honeymoon, I would choose one of those secluded couple for 2 villas on an island. There was one that had only 8 villas on the whole island and you would never see anyone. I need to patch up my relationship with my husband: not that it's bad or anything, just don't hardly have time for each other anymore with the 6 kids and work.
I know money is an object, but I thought I would put this little thing down for fun: I saw a couple years ago that you could rent an island for a week or something. Total seclusion. It was like 8 grand for a week I think? Now that would be amazing.
