Traveling around India is a shock to the system, but it’s not as bad as it looks. If you pay a bit more for the AC3 class on trains (air-conditioned, 3 bunks per side of the compartment), or AC2, it’s pretty comfortable and civilized. Mumbai is worth a couple days before you’ll be desperate to get out, but many parts of Rajasthan are much nicer and fascinating.
And as you mention, Bali could actually work for you. I’ve spent two Decembers in Bali, and December is quite a bit rainier on average. Still I had a great time and it was sunny most of the days. The rain in the tropics (and Bali is almost ON the equator) tends to come down in 30-minute bursts rather than drizzling all day, so it’s usually pretty easy to avoid. The best part of Bali is there are loads of things to see and do, and the nightlife is excellent. The Kuta Beach area is fun for at least a few days, but I wouldn’t spend too much time there. You should also spend a few days in Ubud, which is very touristy but also interesting. And you could spend some time in Lovina, which is along the northern coast and it has all of the charm of Bali from 20 years ago before most of it got overbuilt. With all the temples and other local attractions, there is always something interesting to do, which is not true of many other places with great beaches and nightlife. Let me know if you have any other questions. -Roger
I’ll be happy to try to help, but I’d really need to know your starting point because there are cheap places in different corners of the world, and it’s not worth flying halfway around the world to try to save US$20 per day. In mid December through January for beaches you should consider Thailand and perhaps also Vietnam. I’ll give you more information once I know where you are starting from. -Roger
November can be an ideal month to visit Boracay Island, even though you'll probably see a few quick rainstorms each week. This stunning and laid-back island is in the Tropics, so you can get a quick cloudburst a few times a week this time of year, but they are easy to avoid and the sunsets that form as the clouds are leaving again are often so gorgeous that it's all worth it.
I like your comment about how “rainy seasons” are almost always overstated. I totally agree based on my own experiences and research, although there are a few places where they should be taken more seriously than others. On my most recent December trip to Bali (2.5 years ago, I think), I spent 30 days there and the rain only became a problem that one time I mentioned. It was just an insane cloudburst while taking a minibus from Kuta to Ubud, and in the end it’s actually probably my best Bali story. Aside from that, it’s very humid during Bali’s wet season, but even that really didn’t slow me down. The thing is, in Bali you are usually on or near the beach or a hotel pool (feeling the breeze) or in your air-conditioned room. Or you might be touring around to see temples and rice terraces and whatnot, and everything is outdoors and beautiful. When it does rain it’s usually over in 15 minutes, but often the rain comes over night. That kind of humidity can be a killer when visiting a city, but for me it’s a small issue on a tropical island like Bali.
You may need to skip the cake, or at least limit your intake of sweets and carb-heavy vegetables. Know your body and do what makes you feel best. If you don’t think you will be able to get back on the Keto Diet comfortably after having a “cheat day” or “cheat vacation,” then perhaps it might be best to continue eating a strictly Keto-friendly diet.
Trekking in Nepal during peak season might not sound like the most sensible choice for penny-pinching backpackers. But you can still enjoy the ideal weather without spending a fortune on in-demand hotels and expensive permits if you're happy to swap big-name trails, like Everest Base Camp and the Annapurna Circuit, for quieter treks to Kanchenjunga Base Camp and around the Langtang Valley. Idyllic conditions (dry but not witheringly hot) are also on offer in Rajasthan, one of India’s most vibrant and varied states. Chug between notable, attraction-rich cities like Jaipur, Jodhpur and Udaipur on an atmospheric and wallet-friendly Indian train, snacking on spicy pakoras and sipping sugary chai en route.
