Sinclairs Hotel

I recently started to read about Sinclairs Hotels as part of my hotel industry study. It looked interesting as it had no debt and had a good margin compared to pears. When I looked deep I could not get clarity on following

1. As the company has partnered with STAAH Technology as channel manager which is already used by Lemon tree from 2017 – what is expected for company revenue? Can they go up from mid range pricing?
2. Companies spend ~1% of revenue Advertisement and Sales Promotion out of that I see Pressman Advertising Limited name in related party transactions for Advertisement. Is this common practice common to have ads spent from the related party ?
3. In Annual report 2023 they have mentioned that they are now looking to acquire property on lease which enables to grow faster with lower capital investment. If so, what do they want to do with cash in the form of investment in the MF in the balance sheet?

Appreciate your input.
