DiscoverCars Promo Code: Fuel Rules, Booking Flow, Changes and Child Seats Egypt For All Users

A booking runs smoothly when you know the fuel rule, the booking screens, how to change plans and which extras suppliers can add.

This page explains each fuel policy, the booking flow on the website and app, the rules for changing a reservation and the child seats and extra drivers available.

We took every detail from DiscoverCars.com, its country pages for the Gulf and Egypt and its help centre on 19 October 2026, and we update this page whenever DiscoverCars changes its rules, coverage or policies.

The DiscoverCars Promo Code page for the Gulf and Egypt walks through the practical side of renting: how each fuel policy works, the booking screens from search to voucher, how to change a reservation in My Booking and which extras, from child seats to extra drivers, you can add.

How Does Fuel Work on a DiscoverCars Promo Code Booking?

The fuel policy printed on each offer decides whether you pay for fuel once or twice, so it deserves a look before you compare headline prices between suppliers.

What does Full to Full mean?

You collect the car with a full tank and bring it back full, paying only for the fuel you use at normal pump prices, which is usually the fairest arrangement.

What about the other policies?

Same to Same asks you to return the level you received, while Full to Empty charges for a full tank at pick-up and leaves any fuel you bring back unrefunded.

Where is mileage explained?

Most offers come with unlimited mileage, and any daily kilometre limit is shown under the offer and in the Rental Conditions, together with the charge for extra distance.

1. Filter for Full to Full.
2. Read the mileage line.
3. Refuel close to the return point.

How Do You Book Through the DiscoverCars Promo Code Offer?

Booking on DiscoverCars follows a short flow that takes a few minutes, from the search box to a voucher that lands in your inbox right after payment.

What are the screens?

You search, filter and pick an offer, add driver details and any cover, choose a payment option and confirm, after which the voucher arrives by email.

What does the voucher hold?

It lists the booking number, pick-up instructions, supplier contact details and the price breakdown, including what is already paid and what is due at the desk.

Can you book on a phone?

The DiscoverCars app for Android and iPhone handles the same flow and keeps the voucher, the booking details and the support chat together in one place.

1. Search and filter.
2. Add driver details.
3. Pay and save the voucher.

How Do You Modify a DiscoverCars Booking?

Changing dates, times, the location, the car or extras is done online in My Booking, and most bookings allow changes up to 48 hours before pick-up.

Are later changes possible?

Some bookings, mainly with partial prepayment, allow changes up to one hour before pick-up, and the help centre lists which types qualify for that window.

Will the price change?

A modification recalculates the total at current rates, so the new price can be higher or lower, and you see the difference before confirming it.

What if the change is too late?

Within the final window, the supplier decides whether a change is possible, so calling the number on the voucher is the quickest way to ask.

• Change early for the best rate.
• Compare the new total.
• Call the supplier near the date.

Which Extras Does DiscoverCars Offer?

Extras such as child seats and additional drivers can be requested during booking or at the desk, and their prices are set by each supplier.

Which child seats exist?

Baby seats cover 0 to 13 kg, child seats 9 to 18 kg and booster seats 15 to 45 kg, all subject to availability at the location.

How are extra drivers added?

Additional drivers are registered at the desk and must be there in person with their licence, and some suppliers charge a daily fee for each one.

Are extras guaranteed?

Requests are passed to the supplier, which confirms them by availability, so families travelling with young children should request seats early.

• Request seats at booking.
• Bring extra drivers along.
• Check the daily fees.

How Do One-Way Rentals and Border Crossings Work?

DiscoverCars handles one-way trips by simply letting you pick a different drop-off location in the search, with the one-way fee already inside the total.

What about crossing a border?

The Rental Conditions state whether cross-border travel is allowed, and the supplier's written permission is needed first, often with a fee for extra cover and taxes.

Where does the region stand?

The DiscoverCars Egypt guide says rental companies there allow zero land-border crossings, so drivers in Egypt should plan routes that stay inside the country.

Does the border fee include tolls?

The cross-border fee covers extra cover and taxes, while tolls on the route stay a separate cost that you pay as you drive.

1. Choose the drop-off city.
2. Read the cross-border line.
3. Get written permission.
