Egypt and Thailand are both great options, as February is one of the driest months in both destinations.
Another fantastic option is Dubai. The weather is as good as guaranteed to be great in February, and at a 7 hour flight it is much closer than Thailand. If you are looking for destination with plenty to do then Dubai is perfect for this - some of the world's best shopping, indoor skiing, water parks, desert jeep safaris and sandboarding are just some of the activities available, while beyond that there are some excellent beaches.
