I have seen Josie's romance and it is very sweet. I think with her romance quest + special convo with her sister, it seems rewarding. I actually want to do it now that I've seen it. 
My DA BFF did it for her first romance with an elfy elf, and looved it.
Spoiled myself too, youtube has everything.
And it looks really sweet and romantic, disney romance yup. I might just try to romance her in my next run then, but I'll miss the party banter among the companions for sure in regards to your Inquisitors relationship. Also for variety sake I'll tempted to side with the qunari in this run. Will prob conscript the mages in this run, even though I prefer the Champions of the Just mission, I don't want to ally with the Templars and I disbanded the order in my original run soooo need to try something different.
Also think leaving Hawke in the Fade is a better way to finish off her/his story, quite liked that in my 2nd run when I made that throw away Hawke.
