1. laten we (of wij) naar nederland gaan
Let's go to the Netherlands (there are two ways to say we = we or wij)
The direct object order is different in Dutch (which is one of the many ways - aside from the accent - that they can figure out you're not a native-speaker)
But why would a Dutch person need to say they want to go where they already live? Wouldn't they say they want to gome home (if they are outside of the Netherlands)?
2. Saskia r (above) is right if you mean
let's go dutch=iedereen betaalt voor zichzelf
Although one could argue, you really wouldn't say that too often. I've been caught in several embarassing situtaions when I first moved to the Netherlands. The department manager I worked for asked everyone out to lunch during work hours. I assumed (with my American brain) that if someone asks the department out for lunch that the person (or employer) would pay for lunch. She never said otherwise. At the end of the meal, they whipped out a calculator and started splitting the bill. As my (Dutch) husband later told me, there is always the assumption that you will pay for yourself unless they specifically say otherwise. As a result, there is really not much cause for saying "iedereen betaalt voor zichzelf " because that's a given.
