We will be going to Aruba in May and have been looking at Econo car rental for the week. Any feedback on them as far as having put down a deposit online and was there any trouble with credit card info used online?

Have used them several times and never had a problem.

We just e-mail our request and they gave us a conformation # and had our name down when we arrived. We never gave our credit card on line or had to put down a deposit.
It was the same when we rented a one day Jeep with Ecomony and decided to not use. When we went in to reserve it they didn't even want a credit card to hold. We called the day we were to pick it up and canceled.
Make sure that you do get a conformation number.

I HAVE USED THEM FOR YEARS-NO DEPOSIT-CAR WAS ALWAYS READY WHEN I STEPPED OFF THE PLANE- NEVER HAD ANY PROBLEMS-LAST YEAR THEY EVEN CALLED MY HOUSE TO CONFIRM MY RENTAL

We always call ahead and use ECONO yearly. Suggestion: Put it all on a premium credit card it you can. A gold or platinum one. If you have an accident of any type the card maker will reimburse you. It takes time to get all the paper work in order but I had two claims in 18 yrs and both were paid 100%.
No Insurance for rental necessary.
This advise gets lengthy but I'll try explain briefly. If you hit, damage or whatever or get hit etc. you need to get an estimate from a repair shop. There are several legitimate ones. Then you need a full police report. Hitch: It takes two days to get all the proper info. & paper work together. More time if you have an occurence on the weekend. Having an incident on the last day or next to the last day of your vacation can certainly complicate all of this. I never had that occasion.
You will be required to put the cost of the estimate on your credit card. Pay everything concerning your rental with your card. Keep all receipts, get duplicates and present the costs to your card holder. It takes about 2 months to be reimbursed.

Call your card holder for individual circumstances and verify this info.
When renting, check the vehicle over 100%. Mags wheels etc. many have big gouges and severe knicks, have them noted.
Friends got charged $140.00 for a big gouge they never made. Most have Plastic covers but ck. anyway and note any defects. 95% of renters never had a problem but things happen. Lastly return vehicle with the same amt of gas. and as written here many times:

Make sure you are getting the amount of gas you are paying for. Do the conversion math!

Hope this helps some.

Very nice company no major problems Make sure if you have a child that you have seatbelts in the back seat. Sounds crazy but ours didn't and we had to wait for a car with seatbelts.

Don,

I have reserved a car from Economy Car Rental online in lue of our trip in May, as well. They did charge a 20% deposit to my credit card, but that is all. I've heard good things about them, and they have great rates!

We used them last year and it was no fuss it was fast and we will rent from them again this year
