Hi Lori!
I am very happy to answer any questions you have while planning your magical vacation. Please ask as many as you need to!
I think you would definitely make the most of your time by spending your short day at the Magic Kingdom park. You can travel directly from
Disney's Pop Century Resort to the Magic Kingdom by bus - allow up to 60 minutes for the total journey, but the actual bus ride should take about 22 minutes.
When it is time to travel to Disney's Polynesian Resort, the two quickest choices are either monorail (journey time of approximately 14 minutes), or boat (actual travel time approximately 18 minutes). Don't forget to add waiting times, and time taken walking to/from your chosen method of transport.
To travel back to Pop Century you may find it easiest to travel back to the Magic Kingdom by boat or monorail, and then take a bus back to your resort.
I hope you enjoy dining at
'Ohana!
