I've posted this before so anyone searching Columbus Day weekend threads may find it familiar:
We were there from Wed. before to Wed. after Columbus day 2011. The crowds on the Wed/Thur/Fri before the holiday weekend were fantastic. The weekend was hectic and busy as expected but RD and FP ensured we accomplished what we wanted. The Tues/Wed after Columbus day saw a fair drop in the crowd but still seemed more crowded than the previous week.
To be clear, we were at:
Wed - MK evening only
Thur - MK
Fri - MK and
MNSSHP party
Sat - AK - great crowds mostly due to rain
Sun - Epcot - very busy by the afternoon
Columbus Day - DHS which was the park to avoid but we didn't mind
Tues - MK
Wed - morning MK before departure
We chose DHS with evening EMHs on Columbus Day. We normally avoid the evening EMH parks, but we were only planning a half day there.
We got there at RD, grabbed TSM FPs (1pm return time), managed FPs for ToT, Star Tours, enjoyed the Indy, LMA, and Disney Jr shows, along with GMR, Backstage Tour, and Muppets. Left around 4pm.
TSMM climbed to 80 minutes, Star Tours peaked around 50 minutes, the Indy stunt show was standing room only in the first 2-3 shows, Backstage Tour was 30 mins. Granted it was an evening EMH park with two Fantasmic showings and was the park to avoid.
