My DW and I did this once and really enjoyed it. We saw GF, Poly and CR using the monorail. We took the boat from MK to WL (don't miss this resort). We walked to YC, BC and BW from EPCOT. We were staying at CSR at the time and we used the bus system to get to POR and POFQ (you can walk between the two in about 10 minutes). We haven't seen AKL at Christmas, yet, or CBR, the All Stars or POP. When we did it, the resorts all had gingerbread house displays and the decorations followed the theme for each resort. Have fun!
