There are incremental changes as always in the parks (more pylons for Seven Dwarfs Mine Coaster, a new play area for kids outside Innoventions' Vision House, railings installed at Big Thunder along the track), but the big news this week will be the test of Fastpass Plus, the reserve-rides-from-home technology previously called xPass internally. Part of the Next-Gen initiative to add interactivity and customization to the parks, Fastpass Plus may change much, but we don't know operational details yet. It is starting testing this week.
