I would have been upset if SDD was down the night I went - that was my main motivation in booking the event since, as despite trying really hard, I was never able to get a fastpass and this was my first visit to DHS since it opened. I wasn't able to rope drop that day, so I went to the other end of the day.
I went on 3/9, and I also did the Star Wars Dessert Party, picking up my wrist band immediately following. I did RNR, TOTx2, met Olaf, Star Tours, and Slinky Dog Dash. The listed time on SDD was 30 minutes when I arrived and it took that long, so when I got done at 11:00, I didn't get back in line. I didn't eat a lot (hello, all carbs!), but I grabbed several bottles of water throughout the evening and I was leaving. I drove, but I got a tram all to myself when I was leaving.
I would not book this party again unless there were attractions added that I wanted to do, and even then, I'd have to give it some thought. For comparison sake, I would do the AK version again without a second of hesitation.
