which park first ?- next week - what days will be less crowded?

[stampinbb]

sorry everyone - posted a poll and meant for it to be a topic, new user . . . please reply anyway !
check in 3/25 - offsite
doing both US and IOA for the first time - Is there a better day of the week? Will the parks be worth the lines without FOTL access?
thanks
