Hazel,

Welcome to my forum. The pricing of car rental companies is just as understandable as the price of airfare. No rhyme or reason to the casual observer.   I have successfully used Dooley (among other car companies) with no complaints or problems. If you have a question about exchange rates you can phone them and ask. Or you can choose to put the charge through in euros instead of $$. However, I would check with my credit card company first to see if they levy a "foreign transaction fee" which can be 3% or more.

The code you are using previously gave 10%. Right now it is giving a 5% discount. Better than none.

As for your airfare, you need to weigh your options and do what you think is best. You mention you are departing in the fall. Anything can happen between now and then. Prices might go down. They might go up. Everything I see on the news say gas is going way up this year. They could add a fuel surcharge too. Booking flights are are a game that the airlines usually win. Just like the house always wins in Vegas.
