Boredom beaten: dessert's announced in fancy part of hotel (7,5)

'hotel' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.

'boredom beaten dessert's announced in fancy part' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'boredom' is 'bedroom' which is within the answer.
'part' could be 'te' (te is a kind of part) and 'te' is found in the answer.
The remaining letters 'sui' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

'of' is the link.

Can you help me to learn more?
