I know this is a couple years old, but since you got only one response and might still have the problem (or be wondering about it) then perhaps I can help.
As the other person said, urine does not always smell, or smell as strong. If you ever ate asparagus, you will realize this gives it the strongest and most unique smell. Other foods do this also. Sometimes in the summer if you sweat a lot and urinate only once in several hours it may appear extra strong and yellow. But if have a fever and do nothing but drink water all day it will be like you are peeing water.
You said you were drinking at the bar and went to bed right away (without going to the bathroom first?), and also did not mention that you had a dream that you were using the toilet. All of this indicates a situation exactly as you describe. Alcohol, of course, allows you to retain water, creating a full bladder, while also relaxing the muscles a bit (relaxed muscles is why people like getting drunk, partly, and explains the stumbling). The muscle that holds your urine is also affected by this. It also makes you sleep more deeply so that you would be completely unaware that you were urinating, or even having a dream about it (dreams happen in a different part of sleep: REM).
So the scenario is, you were once a chronic bedwetter and so wetting the bed was not a new thing for your body to experience. The alcohol you drank (and subsequently, I assume, did not relieve yourself of before bed) built up as urine in your bladder, with a slightly weakened muscle, and you went straight into a very deep sleep, and proceeded to wet the bed with the sort of large amount of urine drunk people are famous for passing. The urine was also less yellow and odorous as normal concentrated urine after eating a meal. Because you were sleeping deeply you did not feel yourself wetting, OR (as usually happens in these cases) the cold dampness of the sheets and kept on sleeping. This allowed the extra quantity of urine extra time to sink down deeper and fully soak the mattress as you described, leaving less of a smell.
That probably sums it up! But definitely not sweat.
