Yes, definitely not easy. When we had visiting family so had 2 kids seats in the back I had just one of the rear seats folded up (they are split-food) and a child crawled in via the boot. Works if you’re only trying to fit 6. Workability might depend on how long you will have two full kids seats. If one is older and might move to a booster soon it might be worth putting up with to get a great car…
