Replacement FP+ selections due to Irma

I just got an email from WDW stating that I am being given additional FP+ selections for having to reschedule our trip. They are limited to rides we had FP+ selections for originally but have no time restrictions. In MDE These show up in my Itinerary as ‘Multiple Experiences’ I can’t actually book new FP+'s so can I just show up to any of the rides I had FP+'s for orginally?

Yes. They are additional fps to the 3 permitted pre-booked fps. You can use them wherever you want.

A word of warning. Do not turn up early for any of your existing (pre-booked) fps or the tapstiles will use one your “free” ones instead.
