We are the newbies since we haven't been since before AK and DHS opened. We opted to go for the dining package since we knew our kids (6 & 8 at the time of the trip) would not be able to stand in line for two hours. I started reading on here that it was nearly impossible to get these packages since they have cut the number of shows down. They are still only showing it three times per week at the end of June when we are going. Hopefully they will add more shows during the summer if they see it sold out all of the time, but be prepared that it will be difficult to get this package.
I could not get one on my 90 + 10 day, but calling back on the 90 day from when we wanted to book I was able to get H&V. I had wanted Mama Melrose around 5pm and got H&V at 3:30. I'm just happy to have it though, so we took it.
Good luck and I'd say with 3 & 6 yr olds try to get the package if you can.
