Complex sentence

“She used to stay in a luxurious hotel and entertained her friends lavishly.”
Please help me to modify this compound sentence into complex sentence.
Let the sentence be more elegant.
Thanks.

If the meaning is that she entertained her friends while she was at the hotel:
She used to stay at a luxury hotel where she entertained her friends lavishly.
If it means she did both of these things, but not necessarily at the same time:
She entertained her friends lavishly and she would often stay at a luxurious hotel.
