Oh Hell to the NO. I would not be staying anywhere but a hotel. It's as much as I can do to even VISIT people I hardly know, for more than 2 hours or spend 2 hours out with them (having a meal for example.) I have stayed at someone's house before (who I barely know,) and felt SO uncomfortable and awkward. 
Get a hotel. Even a Travelodge would be better.

I would feel so disappointed if I had a rare chance to visit friends and my DP wanted to cut the time short and stay in a hotel. I love having late night cups of tea and hanging round in pyjamas in the morning. Seeing the weird things people do in their own homes. You say your DP is disappointed. Can you really not cope with it for one night?
But why would you want to put your partner through this if they didn't want to do it? Maybe YOU can stay and they can go to the comfort of the hotel room? I assume you are quite young, because this sounds very typical 'sleepover' behaviour from someone I would expect from someone under 25, not a mature adult.
Most people over 25/30 would find sleeping over at someone else's home, having supper together, and waiting for the bathroom the next day so you could have a shower and a shit, and then having to sit there having breakfast with them very uncomfortable. Especially if they didn't know the people well. 
Even if I know them (and get on with them,) I still would be reluctant to stay.
Fortunately, me and my DH both think and feel the same, we always stay in a hotel, in our own cosy little space, where we can shit and fart and walk around naked to our heart's content. Then sit in bed eating belvita, and supping the complimentary coffee, coz we can't be arsed to talk to anyone, or go down for brekkie.
