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.
Adrenaline junkies should make for Tasmania’s Franklin-Gordon Wild Rivers National Park for roaring waterways and world-class river rafting. Punctuate your trip by exploring the surrounding scenery, from rocky gorges and mountains to tangled emerald rainforests. In Alta the snow has arrived but the crowds haven't, so get there quick to make your mark on some of the USA’s finest ski terrain.
This sounds like a really fun trip you have in mind. I think the challenge is that most of Europe is much closer to 50F than 80F in November, and a good chunk of Europe is already colder than that. I’m running a new series highlighting the best places in Europe (and Asia) to go each month of the year, and I think that the best Europe destinations in November would be helpful to you. Another tricky thing is that you’ve been to many of the warmer places already, and I do understand your boyfriend’s desire to go someplace that neither of you have been.
Hawaii, as you probably know, would be great for what you have in mind, except that there are no cheaper options there at all. After that I agree with you that there are places in Mexico that could work. One in particular that I like a lot is the area around Playa del Carmen, which is just south of Cancun. It’s a lively and tourist-friendly town, instead of a strip of big hotels like Cancun, and there is a wide range of activities and accommodations in different price ranges.
Traveling during the last ten days of December means crowds and exorbitant prices throughout much of the world, but the first two-thirds of the month—before holiday airfares and hotel rates go into effect—can be a serene, value-laden, and just plain lovely time to vacation. Europe is all decked out for the holidays—with locals generally friendly and in high spirits; in the Southern Hemisphere, spring is in bloom; and in the Caribbean, Hawaii, and Mexico, hurricane season is over, the weather is gorgeous, and there are free upgrades galore.
