Welcome to MouseBuzz! You will find tons of information and friendly people here. We love to help plan other people’s vacations, especially when we don’t have a trip planned ourselves! :laugh:
Anyway, as someone has already stated, the Poly is indeed on the monorail system, which makes it incredibly convenient. I’ve not stayed there, but we stayed at Shades of Green, the military resort across the street, and walked through every day. It’s beautiful and exotic, I think you’ll really like it.
I have to recommend one dining option for you, though. My husband and I went to WDW last year for our anniversary, without kids, and we ate at the California Grill at the top of the Contemporary Resort one night. We had 8pm reservations and the fireworks were at 9pm that night. They have an observation deck outside that you can stand on and look at the fireworks at Magic Kingdom. We finished our appetizers, watched the fireworks, then came back in and ate the rest of our meal. Plus, they took our picture and emailed it to us, and gave us free glasses of champagne. CA Grill can be kind of noisy, but we were seated in the wine room, and it was so nice. There are only about 6 tables in there, it’s enclosed, so it was really intimate and quiet. Definitely request a table in there, if you can. It was, without a doubt, the best adult dining experience we’ve had at Disney World. I highly recommend it.
Best of luck with your decisions, and please let us know if you have other questions.
