I will be landing in SIN next week late in the evening and was planing on spending the night at the transit hotel until my UA flight the next morning.

Since I will not be clearing customs in SIN (transit hotel is airside), how can I check in for my UA flight the next morning (or the evening that I arrive)? Is there a UA transfer desk airside that I can use to check in for my UA flight?

Thanks for the help!
