Our rule of thumb is 3 hours from the time we get off the plane to walking into a park. As long as there are no flight delays you should have enough time. Since you are planning to go to dinner immediately after check in, be sure you have everything you need in your carry on since your checked luggage won't arrive until approx 3-4 hours after you check in at Pop.
If you are running late you can take a taxi from Pop to CR, otherwise if there is time, take the bus to the MK, then walk to the CR.
You can only take DME to your resort. You cannot take it to the CR.
