If my experience of endoscopies is anything to go by, 3 of those 4 hours might be a glorious sleep! And another 1/2 hour or so will be waiting.
Is it an upper endoscopy your daughter is having, ie going through mouth to look at stomach? Worth checking as endoscopy can refer to colonoscopy or a bunch of other procedures too, and your daughter might have different preferences depending on what's happening.

I second others’ suggestions to talk through options beforehand. Maybe try to have an initial conversation on the phone with someone a week or more ahead of your daughter’s procedure, and then do it again when you’re there for the procedure.
Worth knowing that there are a few different types of drugs you can have, and they do different things. For example, a friend had an upper endoscopy recently, and was given all three of these drugs:
1. Lidocaine throat spray – this numbs the back of your throat
2. Midazolam – this relaxes you and supposedly means you don’t remember
3. Fentanyl – this relieves pain
I was recently given only midazolam for an upper endoscopy and colonoscopy, and neither procedure could be completed as I woke up choking for the first and was wide awake and in extreme pain for the second. I remember both in detail. Please don’t be put off by this – I expect I would have managed the upper endoscopy just fine on lidocaine alone or with one or two of the others, and similarly I expect I would have managed the colonoscopy had I been given pain relief. I was having a million tests during an unanticipated hospital stay and hadn’t been able to look everything up and know what to ask for. Since I had had two successful colonoscopies in the past, I was not expecting problems with the procedures themselves at all.
And most people apparently tolerate the scopes just fine with midazolam alone. Before I went in I did hear one woman being told that she hadn’t been able to tolerate it – news to her, so I guess the memory-obliterating part worked for her, while it didn’t for me! But everyone else was just being given their results and had obviously tolerated the scopes fine.
It could be worth planning through a few scenarios eg
· What your daughter would like to try first
· What to give your daughter if she’s in pain during the procedure, or if her neck muscles spasm, as you mentioned in your post
Also, if your daughter needs to be lying down as soon as she arrives (eg if she has orthostatic intolerance), then ask for that - they should be able to accommodate her. Explain her needs and a good department should make it as smooth as it can be for her.
Hope this helps you plan rather than scares you. I would have no hesitation doing upper or lower scopes again with different drugs and an agreed plan with a nice team.
