We taped Wishes from our balcony at the GF and I know MANY other people tape it too. The only thing is, after you get home, you watch the parade and you watch the fireworks, and then you don't watch it again until maybe your next trip.
I know that for this year, we are not taping any parade or fireoworks. We find it rather boring to watch after we see it once or twice, at home (I'm definitely not talking about being bored with it AT WDW). We are planning to take a lot more videos of the park itself, and walking around in the parks, so that when we watch it at home, we feel like we are walking around the parks again.
So, after you tape the parade and fireworks, if you have any tape left, get more of walking around the parks. I know we really wished we taped more of the parks. All we have is mostly driving from the airport to Disney, fireworks, and the boats and on the Seven Seas Lagoon from our balcony.
