For Easter week, I'd want to be onsite for the 7 day LL advantage. By the time that 3 day booking rolls around, I think many tier 1 rides may be VERY late in the day or not available at all.
Yes POR or POFQ would be my choice for Easter week. Will you have a car? If not the Disney buses are going to be a benefit over an off-site shuttle for the Hilton.
