I just heard this from a friend who just returned from IOA. We will be there in August and when I booked FOTL and early entry to WWHP was a perk of staying onsite. Is this no longer true?!
You will still get the early entry, but there has never been FOTL for [future? shows how much attention i have been paying lol] Forbidden Journey, or for RRR at Universal studios
In my opinion you will want to enjoy the tour of the castle....so much to see. As long as you use your early access, you shouldn't have to wait too long. I was there on site last July and did Ollivanders first since that line is much slower. Enjoy!!
