I prefer the eastern part of the parking, corresponding to 2F2, rather than 2F1, full of cars of passengers traveling to Schengen destinations for 1 or 2 days only (unlike 2F2 which has longhaul traffic and passengers are less likely to park their car for several weeks).
Not that tricky if you're flying from 2F (rows 13/14 for Schengen and 21/22 for Non-Schengen) - then you are straight at the elevators. Agreed though that it is complicated if you're flying to/from 2E.
The problem with levels -1 and -2 is that you can move easily between 2E and 2F so it is full of London bound day-trippers as well as all the rest who just can't find -3
As a day-tripper myself with lots of very very early flights, not having to waster time hunting for a spot and being close to the elevators definitely makes the whole CDG experience much nicer (much better than the Premium parking ripoff scheme)!
