We are going for the first time to WDW for New Year's Eve. (We are Disney veterans...DVC, AP, MNSSHP, and MVMCP, etc.). We were thinking about doing Epcot on the 30th (our first day...hoping to still get Chip and Dale magnets) and doing the fireworks at 6:30 p.m. on the 31st at MK. How long before the fireworks at 6:30 p.m. should we get a spot on Main Street?
