Sorry if this has been asked before, but it seems the more I read, the more confused I get.

We are heading to WDW the week of Thanksgiving.

I have already planned my itinerary and have dining planned.

Here is where my confusion lies. In the tiered parks for example, say I am interested in one attraction in Tier 1 and only one attraction in Tier 2. Do I have to pick 3 fast pass options or just 2 attractions.

I am so confused.

Thanks for your help in advance.
