When we used the $25 Planet Hollywood voucher in September there was not a set dollar amount you needed to spend. However, let me add that the prices are way too high there. Our son got a kids chicken finger meal and it was around $8. I think our total bill was around $35 - $40 and all we got were 2 adult lunches and 1 kids meal with non-alcoholic drinks. The food quality was average to below average. It was the only non-Disney restaurant we ate on during the week and it was a disappointment. However, it was the only choice on our flex option that we wanted to use.
