My husband and I did an all inclusive to Cancun last fall with our son, his wife and two of our grandchildren. So best of all worlds - lots of time with the grandkids, but I also took my Kindle and sat on the ocean by myself while the non-alcoholic drinks kept coming. Hubby and I wanted to do different excursions, so I went to see Chicheiza and he went snorkelling. I admit I didn't like being without him. I got stuck in a non seat at the back of the bus, I was the only person by myself. But I loved the pyramids, it was worth it. Cost of our trip was $2500 Canadian for both of us. That was pretty good we thought.
My daughter and her husband just got back from Hawaii. They both loved it, and highly recommend it. They rented a condo, and cooked a lot of their own meals. I think an all inclusive in Hawaii is pretty pricey.
As for the Arctic, I don't recommend it. Flies and mosquitoes! Boring scenery. Our oldest son lives in the Arctic. For Northern Lights, probably Edmonton is just as good. We saw them all the time there. And there is the second biggest mall in the world there. Then there was Saskatchewan in the dead of winter - 40 F or C. That was an entire prairie sky filled with red and green lights. I actually got out of the car and just watched. Something I will remember for the rest of my life.
