New Zealand will also be crowded, but the country is otherwise mostly empty so it is still wonderful. You could fly to Auckland for one day or so and rent a campervan/motorhome. Drive it for 3 or so days on the North Island, and then onto the ferry to the South Island for the rest of your time. The South Island is far more scenic and less crowded. You’ll be doing some driving and looking, but after a few hours of that you can stop at a campground and have plenty of things to do such as hiking or water sports and much more.
The rainy season usually ends early in November in Siem Reap, and the tail end of it is rarely fierce, so this is an ideal month to hang out in town and spend multiple days at Angkor Wat. November is actually the coolest month of the year, by just a bit, at least during the days, so most people will appreciate more moderate temperatures when climbing up and over all the temples.
While December is quite busy in Lima, as a very popular summer beach destination for South Americans, it's also still very reasonably priced so it's worth considering if you are exploring the continent. The beaches aren't spectacular as they are in Brazil and elsewhere, but Lima is still a great summer city with great outdoor life this time of year.
Your Munich plan sounds good. It can be fun to actually spend a full night in a town like Rothenburg ob der Tauber because it’s filled with day-trippers in the day and you almost have it to yourself at night. But it’s small enough that one night there would be enough. Nuremburg is quite a large city, and you might even stay there a night or two as well. I don’t know if I’ve ever heard of anyone saying they enjoy the cold and the rain, but if you do you’ll love it there. Fortunately, nowhere in the popular parts of Europe do they get extreme winters, and there is a good chance you won’t even see any snow in those cities. Most people are looking for the warmest places, which can be found in Portugal and Spain, but since that isn’t you I think your plan is good. Christmas is a big deal in some European cities such as Rome, but not a huge deal in others. Most businesses will be closed that day in nearly all countries, but of course hotels and many restaurants will be open. I hope this helps. Let me know if you have any other questions. -Roger
We flew with EasyJet and I was pleasantly surprised at the availability of keto food on the flight. I got a tapas box which had jamon serrano, chorizo and a tomato salsa that was, amazingly, sugar free! It was plenty to keep me going until we had dinner at the villa that evening. I didn’t track my carbs on this trip because I was eating keto the whole time so even when I went over slightly I wasn’t massively over. I also spent a lot of time swimming in the Mediterranean Sea and it was so hot I think I must have lost 5lbs in sweat alone! Sorry.
It would be hard to beat Chiang Mai for its combination of great November weather and low prices. Even though it's officially the start of the high season for hotels, the beginning of the month is usually very slow anyway, so bargains are common. Hotels in Chiang Mai are among the best bargains in the entire world, so even if you do have to pay full price for a room it'll be cheaper than a dorm bed in most European cities.
Thank you so much for the kind words and I’m always happy to hear that people find this information useful. As far as Turkey in December is concerned, I wouldn’t recommend it. I actually lived in a small town near Antalya on the Mediterranean for a bit over a year and I was surprised by the fact that almost everything closed down around 1-November and didn’t start opening again until March or April. Actually, I think Istanbul would still be enjoyable in December and so would Bodrum or any of the other larger cities including Antalya. But anywhere on the coast will be a ghost town and I’m pretty sure that Cappadocia would also be mostly shut for the winter. Ephesus probably stays open, but similar to Cappadocia, the attractions are all outdoors and they can get pretty fierce rainstorms in winter.
I totally agree about the solo traveling thing being down to luck in many cases. Right now I’m on a long trip around Europe again, and from one night to the next I might meet a bunch of interesting people, or be sitting there alone in a sea of locals with no interest in chatting with foreigners. At least in a place like Goa, everybody is on holiday, so I’ve had good luck meeting people.
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.
