I can provide some insight into why the hotel prices are different (I run Room77, a hotel metasearch site). Generally, many hotels enforce a parity price display rule with their sellers (think Minimum Advertised Price) so the travel sites aren't supposed to market a rate below the market price. There are exceptions built in for "members only" clubs since these users are gated and allowed to get a non-public rate. There are also exceptions in some cases for mobile rate discounting since they are generally last minute and if you have the app installed you could technically be considered part of a "club".
