Bee Taechaubol's luxury hotel suite in Milan is booked until Thursday.
Gazzetta dello Sport says Mr Bee expects a decision from AC Milan owner Silvio Berlusconi over his takeover bid on Wednesday when they meet.
Interestingly, it's suggested Mr Bee has slashed his consortium's offer since examining the club's books.
The original offer was €750 million for 65 per cent of Milan. But Mr Bee will make a bid of €500 million for 60 per cent of the club tomorrow.
Berlusconi, meanwhile, is also in sale talks with Chinese businessman Richard Lee.
