Had similar problems too ... most times I get K1 to drop me off so doesnt matter but have been trapped and had to drive over the grass to get out once.
Badly designed and if they redesigned the parking bays could increase existing capacity by 30%+ ... even so a bigger car park or a long stay car park somewhere nearby would be a welcome addition.
Only + side can say the the 50 Baht/day is about the most reasonable airport parking anywhere on earth! Been no price changes in all the time I've lived here ...
