Guild Wars 2

Topic says it all. Can you go in with just one or two players and manage it?

Yes, I 2 manned it with a friend

In fact i would say it is easiest to solo it.

And if you are feeling unsure, you can talk to the cloud inside the first building for "infantile mode" to get a feel for the level layout and puzzles. You should be able to speed through that solo and make a decision about normal mode from there [likely that, yes, you will be fine alone or in a group].

I soloed it and was fine doing it.
so yes you can solo it if you want to.
