The holiday companies love advance bookings - they've made a sale, and you've got time to plan - so plenty of the big names offer sizeable discounts and freebies to early birds.
For example, Airtours guarantee to knock £75 off January bookings and have a number of summer holiday deals, while both The Co-operative Travel and First Choice have free child places available to advance bookers.
Elsewhere, book with Onthebeach and you'll benefit not only from free child places but could bag a serious bargain with up to 50% off your hotel, so it's worth checking what's available before you make any firm decisions on destinations.
Another good reason to get your booking in early is that many travel companies allow you to put down a small deposit (as low as £60pp) and some will even offer payment options, allowing you to pay for your break bit by bit.
Even if you prefer to tailor-make your break by booking flights and hotels separately, the earlier you book, the better the flight price is likely to be so do check online comparison sites to see where the best deals are.
Of course, there are many other advantages to booking your summer holiday early, not least that it allows you to save up spending money as well as pay for the break monthly rather than in one lump sum. And if you're a savvy shopper, you'll know that buying all those summer sun essentials during the cold weather could save you some serious money too.
