I'm sure some people will think these are minor issues but to us they were pretty major.
I have a dietary issue in that I'm allergic to dairy. Allergic enough that I have to carry epipens with me. Disney was notified of this issue and I confirmed it with the guides at check in. We even went over in detail exactly what I could not have, as I cannot have any kind of dairy. I'm not just lactose intolerant, I'm actually allergic to all kinds of dairy - milk, cheese, yogurt etc. So this was a known fact to the guides that I could not eat anything that contained any kind of dairy product or by-product in it. And yet, this seemed to slip their mind when we were on the bus transferring between cities since they never ensured any of the dairy free snacks were available to me on the bus. They allowed everyone else in the group to take multiples of the fruit before they ever even got anywhere near where I was sitting on the bus so that by the time they did get to me, there was no fruit left as options and what was left all had dairy listed as ingredients. They didn't even offer to go and bring me a fruit. It's like they completely forgot they had it. I never even knew they had fruit until it was mentioned in passing during a conversation one day. If I hadn't thought ahead and packed my own snacks, I would have had some very hungry and very long bus trips.
Another major issue we had was on the bus ride from Berchtesgaden to Mondsee. I don't know exactly what the topic of the discussion was supposed to be about exactly, I just know that the guides decided to play German rock music turned up full blast while we were on the bus. When we complained we were told that it was the only time they had to have this discussion/talk. My mother and I spent a horrendous 2-3 hour bus trip in the back of bus in tears because the music was giving us migraines and the guides refused to turn the music down. We were not asking them to turn the music off, just play the music at a more respectable level. We were trapped inside a moving tin can with no way off. And yet, when it came time to play the "funeral music" as a fellow tour member put it, i.e. the classical music that Vienna is known for, the guides had no problems playing that at a much quieter level.
I plan on reporting these issues to Disney because apparently their philosophy of being for the enjoyment of all guests does not apply to
Adventures by Disney.
There were a number of other, smaller issues but these were the 2 major issues that have basically sealed the deal for us when it comes to not travelling with ABD anymore.
