At the risk of this turning into a thread of everyones opinion... ill toss in my two cents to
@echino 's ranking... Given you are booking within 8 months Id rank them as follows...
OF S >
OV N > OF N > OV S > IV N > IV S
To the points made above, there are OF N Views that are right behind the food truck, and given the timestamp that risk is even higher... All the OV N rooms are basically in building 7 facing out over the park between KORVN and Nanea, all of which I would take over a food truck view. If you want to mitigate risk and your view matters to you, that's my personal opinion I thought I'd toss in...
All that said, you never know... the best view in either OF far exceeds that in OV... Luck could be on your side!
