In Rome, the Coliseum and Ancient Rome are outdoors, but the city also doesn’t get as cold as the others so most likely you’ll be fine if you bundle up a bit. In Venice, they often have those floods during December, but they come and go every 6 hours so even if you get unlucky you’ll still be able to get around half the day, and it’s a small city anyway.
Thank you for the kind words. Interestingly, had you not included that you’ve been to Costa Rica, I’d say that was the obvious suggestion because they really do that sort of thing well and it’s at least a bit better organized than its neighbors. And if you were less concerned over travel time, I’d have some interesting suggestions for you in Asia. However, as you know, it takes nearly a full day just to get to Asia from the US or Canada, and then a few days to adjust, so you might be best off saving that for later.
I’m sure you’ll have a great time. I don’t have any good suggestions for where to celebrate Christmas, but I’m sure you’ll have no problems finding something by just walking around or checking online. The top draw in Barcelona is the architecture, and especially the 20th Century buildings by Gaudi. I recommend the hop-on, hop-off bus tour because it allows you to see almost all of the famous buildings from the street in just a few hours. Park Guell is worth a visit, but of course the main attraction is the Sagrada Familia cathedral. Check opening times and reserve a ticket in advance if you can.
Yes I travelled a bit by train in southern India, I got lucky on my first few journeys with lack of people, then I hit some Indian holidays and it was hellish. I remember the trains being booked up for all the upgraded a/c and upper class carriages. One time even the Indians were fainting on the over packed carriage so you can imagine the heat for little old gringo me!
If you do want to go to Thailand then Bangkok is the obvious starting point and it’s a wonderful city. You also want to visit Ayutthaya, which you can do on a day trip but it’s better to stay a few days. Chiang Mai is the highlight of the north, partly because it’s insanely cheap and the weather is a bit cooler than Bangkok. Luang Prabang is another town not to miss and it’s fun for at least a few days. Don’t bother spending much time in Vientiane though.
If you are going to that region I suggest you visit a site called travelfish.org, which is by far the best website on SE Asia and it’s run by a friend of mine who lives in Bali. They have busy forums where you can ask questions and quickly get them answered by experts on every imaginable topic there. I’m happy to help more as you are planning, so let me know if you have any other questions. -Roger
This is a difficult question to answer without quite a bit more information. First off, it’s obviously going to be pretty cold in most of Europe that time of year, although most of the major cities aren’t known for accumulations of snow. As long as you are okay with cold weather then it’s mostly down to budget and your main interests. I’m guessing that you haven’t been to Europe yet since you didn’t mention any places that you’d prefer to skip this time.
Late October (when the rains end) through February is an exceptional time to visit the northern part of the country, from Sukhothai through Chiang Mai and Chiang Rai. The King’s Birthday, on December 5, ushers in the festive season (Christmas and New Year’s certainly aren’t traditional holidays here, but many Thais celebrate them anyway) and cooler, less humid weather. In general, the beaches are blissful from the end of December through March. Mid-November through January see the lowest temperatures and least humidity in Bangkok.
The last suggestion would be to start in Bangkok, which is an amazing city even if you avoid the Khosan Road party area, and then head south along the coast and into Malaysia and finally Singapore if you feel like it. There are many nice beaches and islands in Thailand that aren’t filled with party folks, and some really interesting places in Malaysia as well. George Town on Penang is really nice with excellent food, and Kuala Lumpur is my favorite city in Asia for few reasons. The town of Malacca is really nice, and Singapore is amazing, if a bit expensive.
