From the Forex card website:
A Forex card can be used in the same way one uses debit and credit card. When you are travelling abroad, you can use the Forex card to pay hotel bills, make purchases at various shops, restaurants and online sites. You simply need to enter your PIN or signature to complete the transaction.
Therefore, you would use your Forex Card the same way. There is no harm in trying to use it. Some hotels may reject it due to the fact that they require specific payment methods.
