Haha what do you mean by getting through the trip comfortably? This may be a meme but I swear on the fact if I dive air I feel wiped out. Nitrox I feel better.
I think it's worth the extra money, you should get significant better bottom times at the end of the trip...
Nitrox works fine for me too. I made 25 dives in 6 days no problem. I saw guys dove with air got tired and skipped dives.
