I currently own a NX-250 and am toying with the idea of moving to a Flex-180 so that I can bring child with me on trips. I have been searching forums and videos and there still does not seem to be a lot of information out there on the Flex-180 (there is some for sure, maybe I'm missing the rest?).

The questions:
(1) It does not seem like it would be a big deal, yet I am curious if people who own the Flex-180 have found the single side entry/exit a problem? Is it troublesome for a person (child or adult) to access the second bed area?

(2) Anyone out there who regularly back-packs with the flex-180? Is the extra space worth the weight (I'm a fairly small guy)? Am I going to want to keep the NX-250 for solo trips and have the Flex-180 for occasions when one of the children are with me?

Thanks for any feedback.
