Joining

I am a senior software engineer. I have previously worked at companies with unlimited PTO. Two of them had real unlimited PTO but the most recent I have worked for (Adobe) has made it clear taking vacation days is discouraged/does not lighten expectations. I am probably joining a new team at a different company. Final round interviews went great and I will be hearing back soon. They are FAANG and there I would be accruing PTO slowly at the same rate as a new grad hire. I am not sure I can handle the time off aspect of the job long term. I love to travel and need time to recharge and keep my creative pursuits going. I will of course try to adjust to the lower amount of PTO but I worry I may not last long going that route. The team seems great and I am already friends with the manager as well as some folks on the team. To me the pay is not so much the issue but having time to recharge and travel is. I would like to ask for maybe a week or two of separate unpaid time off yearly. I can give plenty of notice. I get that adds complication for things like benefits but is there a world where asking for this would be acceptable? How much of an ask is this to a manager? Most HR portals make it seem like taking unpaid time off is just as easy as taking PTO... but in reality... is it a bad idea to use unpaid time off? I have never tried. Does this throw a significant wrench in planning?
