We did many w/o Express, but now I think the family always wants it. I'm the oldest and I think we do not need it. BUT, we go multiple nights, if we can get RoF and do four consecutive, we really only have to try for four houses a night, adjust based on what we liked. I always find myself blind during S&S and feel I miss out on a lot of detail in the mazes (I know this based on what I can see later in the night...this is because my eyes do not unjust quick enough...need to remember the shades.
Anyway, we we've had Express, I do not think we get any more houses done...my family just ain't the commando type I guess...but yes, RIP on a Sunday would be a way if we only went one night (which would save plenty off the hotel stay)...hmmm...wonder if the BOGO let's you use the first night on a SAT and then a SUN for the free one ;-)
But it always seems hard as heck to get a room for under three or four nights during HHN season...man, this is starting to feel like thinking/planning....sux being a fan these days ;-)
