I agree, but just make sure that it says "nights". On my Disney UK our 14 night package shows as 15 days, which is correct as they count your arrival and departure day. It won't hurt to double check over the phone anyway though.
Ha! I did the same thing which is how I knew to suggest you check that. Of course I wasn't bothered about spending an extra day there and had no intentions of calling to find out, prior to re-reading the text.
