What is necessary for a Hotel to accept Bitcoin as a payment method? I manage a hotel and the owner is interested in using Bitcoin as a payment option. How can we start to use this option and what will we need? There are multiple hotels he owns and would like to eventually get all of them using this option as well.
Depends on your budget or technical expertise I guess.

A. Install a wallet and create a new address. Post this address on the hotel's website and you are ready. This is the low tech solution and you would manually have to check the balance to see what payments are received.

B. Use a gateway like BitPay. It works like a Paypal for Bitcoins. The payment will be handled by BitPay and BitPay will send the coins to your address or convert them to fiat currency for you. This is probably the option you are looking for but BitPay takes a little fee of course. Coinbase or BIPS are alternatives.

C. Hire a developer to do the integration for you. This lets you customize the way you want it but is probably way more expensive.
