OceanGate's cofounder wants to send 1,000 people to a floating colony on Venus by 2050, and says we shouldn't stop pushing the limits of innovation::Guillermo Söhnleinm told Insider he has wanted to make humanity a multi-planet species since he was 11 years old, and that OceanGate was part of that ambition.

Based on the Wikipedia article ( https://en.wikipedia.org/wiki/Colonization_of_Venus#Advantages ) it doesn't seem like that's the case. Optimal launch windows are more frequent and flight time is reduced (although it's not a massive difference). That section doesn't specifically mention delta v or fuel requirements but I assume if there was a notable difference aside from the flight time part that there would be something about it.

I'm far from an expert, but I'd guess in a way stuff like fuel requirements don't really vary that much with distance, just time. This is because the vehicle will accelerate to some set speed and just coast for most of the way before decelerating at the other end. At least with current rocket propellant-based approaches, it's not feasible to include enough fuel for the thing to be actively thrusting for more than a fraction of the total time.
