Cambodia could work because Siem Reap is inland and the amazing Angkor Wat temples are worth a full day or two, and the town of Siem Reap itself is quite nice. You could actually combine a couple days in Siem Reap with a few days in Bangkok, and take a (cheap) luxury bus between the two. Bangkok is a really fascinating city with a lot to see, plus it’s a great transport hub. The other main non-beach option in Thailand is the city of Chiang Mai, which is wonderfully inexpensive with quite a bit to see. It’s even a bit cool during December, so that might be a nice change of pace from India. Many people are also going to Myanmar these days, although I haven’t been yet so it’s hard for me to recommend it. I’d say if you combined 2 or even 3 of these places you could have a very interesting holiday.

I think Sri Lanka would be wonderful for 2 weeks in December. The rainy season typically ends early in December, but even when it’s still going it tends to be quick downpours, as you are no doubt familiar with if you’ve been all over southeast Asia. Still at this point there are very few hostels with dorm beds and not even many cheap budget hotels, but at the age of 30 you are probably happier with normal hotels anyway. Value is quite good in Sri Lanka as long as you can spend at least US$30 or so per night, and hopefully a bit more. Food is also quite cheap in general, although there are still surprisingly few tourist-oriented restaurants in many towns so it feels a bit undiscovered. Just don’t spend much time in Colombo and preferably focus on the mountain areas, and I think you’ll love it.
Those wanting to hike to Machu Picchu will also find this to be an ideal month, since getting in a group will be easy even without much advance notice. The train to Machu Picchu is expensive year round, and reservations should be easier to get the day before this time of the year. Hotels are always cheap in Cusco so you can afford to get something nicer than you are used to this month.
I’ll be happy to try. First off, if you are doing the actual Inca Trail hike, you’ll need 4 days for that plus another couple of days in Cusco to get acclimated. So really that whole part of your trip would be a week. Also, to get to Cusco you pretty much have to go through Lima, and it’s also an interesting city so I’d recommend probably 2 nights there. If you don’t do the Inca Trail and take the train instead, you could save 3 days in Cusco.
Located off the coast of East Africa, the Seychelles—an archipelago consisting of 115 islands—is about as close to paradise as you can get. Crystal clear water, lush jungles, and powder-fine sand make it the ultimate early winter escape, particularly for romantic getaways. Book one of the 30 breathtaking pool villas at Six Senses Zil Pasyon, which is among the region's top luxury resorts. The hotel is situated on a private island that offers prime territory for snorkeling, sailing, kayaking, and hiking—plus, the spa has scenic pavilion-style treatment rooms that are worth the trip alone. Health conscious guests will be particularly impressed by the property's new "Eat with Six Senses" program, which is intended to make travelers leave vacation without the guilt that comes with overindulging. There are four tailor-made treatment plans that focus on sleep, detoxing, fitness, and more, depending on the issues you prefer to address.
