Hi, you said returning to the island - did you rent a car before, if you were happy with the car and service - why change
Note re pricing - not sure, but I think Ace is Safari
Make sure your quote is all in, tax, liabilty etc

No experience with ACE, but the Safari on line price starts really low, then ends up higher than the price I have this winter from the person we've used before

If I was happy before, I wouldn't change unless lots of $'s saved and excellent referrals
If not happy before, not sure I would attempt to solve that based on price alone
