Why do you get into these dilemmas?
Because they are the BEST! First the joy of picking a vacation, followed by the fun of planning a vacation. (Oh, yeah, and the pleasure of the actual vacation!)
Last year when my mother suggested that my family and my sister's family join her on a vacation, we had each of my two son's and my sister's two daughters pick a suggested location and do some research on it, and prepare a PowerPoint presentation of their choice, complete with options, costs, advantages, disadvantages, etc.
Then, when we were all together at Christmas time, they each presented their slideshow to us and made their "pitch." Los Angeles, Orlando/WDW, and Yellowstone/Badlands/Mt Rushmore, were the other three pitches. For our family, we chose the Fantasy over WDW and the others, so that is what we would do, but no matter what you choose, deciding will be great fun.
We loved our trip, but we'd still love to do any of the others. But by exploring all of the options, in a small way, we got to enjoy a bit of each of them.
Thanks for sharing your dilemma! This is the kind of "problem" that gets better when shared!
Tell us what you end up picking!
