I emailed them a bit ago and got the same offer, $125. Since we'll be on Aruba and Bonaire as well, I've checked prices for renting a car for the day there too... ~$75 - $100. I expect the higher prices are due to the fact that they are only a one day rental vs several days. Oh well.
So, are they somehow charging as a two day rental with whatever taxes, etc? We'll be there, as well as Aruba and Bonaire in September, so trying now to just get things reserved.
Thanks!!
