I always use the drip method when ever receiving fish or changing tanks. Takes around 1-2 hours and I use a 5G bucket with airline tubes/air valves. Initial water level in the 5G is maybe 6". I siphon directly from the tank (you can see more in my yahoo album under the discus folder) and once full I net the fish. I think it is a much better way to climatize then the float/fill/wait method from experience (fish seem to 'recove' much quicker).

When climatizing to large water parameters differences, I usually slow the drip so it will take around 4-5 hours to fill the 5G bucket! However, I also add a heater! I would not recommend doing it any longer than 5 hours, never mind a couple of days because then your looking at having to add filteration, aertion, heating! The only time I would take longer than 5 hours to climatize is if the ph is quite a bit lower than the tank (more than 0.5)!
