I don't want to judge an entire nation based on a group of 500, but the Dutch are a very rude and pushy group.
Now, one of my previous tour guides was Dutch and even though she seemed a bit brusque and standoffish, after a few days I broke her and we had a lot of laughs.
But this group will knock you down just to get on the bus before you.
Personal space .... They have no idea what that phrase means! I was in line one day to get on the bus and I went to put my hands behind me and BOOM! she was so close to me that I could clean the lint from her belly button! SERIOUSLY!!!! So, being the nice American that I am, I took a step forward. YEP!! You guessed it; I turned sideways and whacked her with my shoulder bag (which isn't very big). Maybe she just wanted to be close to me?
Greeting....good luck. Enter an elevator, six already in, say 'hello' and listen to the echo! UGH!!!!
Listen to a presentation ..., they'll carry on their own, regardless of who's around and they're not whispering.
Aussies, Brazilians, Brits, Spanish....LOVE THEM!
Never say never, but I will never again take a trip out of Rotterdam.
