Fortunately, Bangkok remains very cheap by almost anyone's standards. If you want to splash down for a nice 3-star room then it'll be half the price of a similar room in Europe or the US, and if you are fine with something more basic then you can find a room for next to nothing, even in the fun Khaosan Road backpacker district. Street meals for around a dollar are always there too, so you'll be able to afford a bit more for a room anyway.
Thank you for the insightful details about South America and the others! Peru, Costa rica sound ideal! Always wanted to work at a sustainable place is Costa Reecs. However, I am also quite interested to know what Brazil , rather the different parts of Brazil are like, since it is so huge would be interesting to visit during the same time of the year.. Since I love and play Capoeira too, I’m pretty tempted to visit Brazil and draw inspiration. 🙂 And what is Colombia like?
Always happy to hear that people find this useful. If you are looking for a driving holiday with warm weather in December I think you’ve already narrowed down the best choices. New Zealand will be ideal, although maybe not for more than two weeks or so. As you might know, the South Island is more scenic than the North, but the North has many great things to see and do as well.
But if you wanted more to explore the area near Singapore then Malaysia and Thailand are the obvious choices. The three most popular stops in Malaysia are Malacca, Kuala Lumpur, and George Town on the island of Penang. I quite like all of those so it’s hard to recommend one over another. I really like Kuala Lumpur and have spent quite a bit of time there, but honestly compared to Singapore it seems a bit untidy and old fashioned. In other words, if you are tired of a big and busy city like Singapore, then don’t plan much time in KL. Malacca and George Town are both smaller tourist cities with great food and interesting sights. There is frequent and cheap bus service from Singapore going through Malacca and onto KL. Then more buses from there to Penang and onto Bangkok.
However, I also happen to be an athlete and about a month ago I reached the point where I had almost no power, no energy, constant hunger (and “hanger”) and cravings for practically anything bad like alcohol, sweets, carbs, artificial sweeteners or energy drinks. I tried to fight it. I started over multiple times. At one point I just couldn’t stick to any sensible dietary routine for longer than a day or two. Intermittent fasting, OMAD (one meal a day), TMAD (two meals a day) and keto all seemed to stop working.
If your real goal is to sit on a European beach and not freeze or be alone in December, your only real choice is the Canary Islands. Tenerife is the largest of them, and the best one for English speakers. The average high in December there is 22C with 16C as a low, and in December it’s packed with Swedes and Brits and Germans who actually do sit on the beach or around pools, even though it’s a bit cool for most of us. It’s important to note though that the Canary Islands are technically part of Europe because they are a territory of Spain, but only the largest cities on each island are “European” at all. The beach resort areas are quite generic, and not very special aside from the pleasant weather and modest prices.
As for alternatives you might consider Argentina, where of course it will be late spring in November. Buenos Aires is a wonderful city and recently they’ve been going through a financial meltdown again so their currency has dropped a lot, making things unusually cheap again. You could spend 3 or 4 days in Buenos Aires and the rest in the Mendoza wine country or Iguazu Falls or Bariloche for some adventure. From everything I have heard it’s all safe and civil there, so it’s just a matter of the local currency going down in value.
If you’re a bit more on the timid side, you can always use Yelp and TripAdvisor to get good insights on places people have visited. As a disclaimer, some of the ratings may not be accurate on these sites, so make sure you go through and read some of the more recent reviews that people have written. We did this for a few of the places we visited and had no issues.
