My favorite part of Bali is now the area around Lovina along the north coast, which is still very mellow and mostly open spaces with light development. It’s really beautiful and there is plenty to do. You can get similar experiences by visiting the nearby Gili islands, which also feel like Bali used to be 20 years ago when it was much nicer. They are all really beautiful and relaxing islands with great scenery and very friendly people. You just need to steer clear of the places that are the most crowded.
Interestingly, December though February do get a bit cool in Cairo, so it's not a great winter break, but in November it's still pleasantly warm and bone-dry so you can enjoy the outdoors for long periods of time. If you don't mind staying in a locally-owned hotel you can save a lot of money and see some old-world charm at the same time. Reservations in advance aren't necessary, but it's best to book your first couple of days just to avoid all the confusion once you arrive.
Traveling during the last ten days of December means crowds and exorbitant prices throughout much of the world, but the first two-thirds of the month—before holiday airfares and hotel rates go into effect—can be a serene, value-laden, and just plain lovely time to vacation. Europe is all decked out for the holidays—with locals generally friendly and in high spirits; in the Southern Hemisphere, spring is in bloom; and in the Caribbean, Hawaii, and Mexico, hurricane season is over, the weather is gorgeous, and there are free upgrades galore.
