November is the time to catch the last days of spring’s moderate weather and prices in New Zealand. Temperatures vary during the month, but average in the high 60s with relatively dry weather in most areas. New Zealand's spectacular scenery invites outdoor activities, and November is the perfect time for hiking, biking, river rafting, and exploring the national parks, forests, lakes, mountains, beaches, and thermal reserves. Fresh seafood including green-lipped mussels, crayfish, oysters, and finfish, as well as lamb and award-winning cheeses are served in local restaurants.
Thank you. I think Kauai, Cancun, and Costa Rica could all be good choices for you. You’ll be looking at the last month (more or less) of the rainy season in each of them, but in the Tropics that usually means at most a few quick thunderstorms per week that typically last only 30 minutes or so. Kauai would be the most expensive of the three, although the most beautiful as well, and the easiest to visit since Spanish isn’t necessary at all.
The high season hotel prices will start in November as well, but crowds are usually thin for most of the month so you should be able to get some nice bargains at some of the nicer places that allow online booking. When they see that they have lots of empty rooms as the month approaches, they'll discount to be on par with some of the 2-star places that aren't nearly as nice.
If you book a resort hotel from home you'll probably think Goa hotel prices are much higher than you were expecting, but if you book a family-run place once you arrive you'll still find fantastic bargains. It's probably wise to book a few nights online before you get to India, because it can be incredibly confusing at first. After that you might be able to find a similar place for half the price by just checking around the same area.
Since flights to Mexico City from the US and Canada are usually quite cheap this time of year as well, this could be a perfect short cultural holiday. This city has great shopping, dining, and nightlife, and the central historic and tourist districts are far safer than most people would expect. There are ruins just out of town as well, so a bit of everything is available.
