I assume that by "it" you mean the Model S?
Keep in mind that when you have 7 people in it, at least two must be relatively small (77lbs or under) children. So the added weight isn't quite as much as it sounds.
The P85D weighs just under 5,000lbs empty. Say your 7 passengers add 1,000lbs of weight, that's a 20% penalty on acceleration. Might be noticeable, but performance will still be extremely good.
As for range, aerodynamic drag dominates at highway speeds, which is where you'll be spending most of your time on a trip. The efficiency hit from extra passengers will be down in the noise. You could probably recoup it by driving 2MPH slower.
I haven't done a long trip with 7, but I did do a reasonably long road trip with 6 in my Model S, and the extra weight was not noticeable. You don't want to be flooring it in a powerful car with small kids most of the time anyway, and the energy use predictions were still spot on.
