LOL! I did this exact package change
For me I think it's going to be worth it. When are you going? Since I'm going for opening I figure the lines to get in are going to be insanity for the first week especially and having Happy Entry will be worth it to avoid that for the most part. Plus I'm sure I will need a quick afternoon break and it will be so convenient.
Check out views on Youtube, Chris from TRD Explorer did a recent video on vacation packages and he had this exact room. You can watch Believe! from your room, see rehearsals, etc. I'm someone that tends to splurge a bit on Disney rooms though. I don't spend a lot of time in my room but I've never seen rooms as just a "place to sleep" like some people do.
