15% off Hotels.com (UK site) booking when you pay with Mastercard. First 2838 customers only!

Until 31st January 2019 Hotels.com have a 15% discount code for the first 2838 customers who book through their UK site.

Your stay will need to satisfy the following conditions:

• Voucher only valid for the first 2838 customers only.
• Book before 31st January 2019.
• Stay before 31st July 2019.
• Must be UK resident, although in practice I believe this only means you need to book through Hotels.com's UK site.
• You need to pay with a Mastercard. (Make sure you put in your Mastercard payment details before you enter the discount code)
• Booking of between 1-3 nights.
• You cannot collect or redeem Rewards Nights when you use the coupon.
• Payment in advance and in full.
• Maximum one coupon per booking, and only applies to the first room in the booking, and on the pre-tax prices.
• Voucher can be used maximum of 5 times per customer. (So if you travel and share rooms with a partner a lot, then make sure to create an account each.)
• One of your 5 coupons is deemed when you book a hotel, even if you cancel it later.

There is quite a long list of non-participating hotels so if your voucher does not work and you satisfy  the above terms, make sure you check whether your hotel is on the list.

You will need to input the discount code “MC15UK” at checkout on the right hand side. If it goes through your booking page should show something like this.
