We plan on registering for a few items (he already owns his home so he pretty much has everything) so we can have a registry for the shower. But instead of gifts for the wedding, we'd prefer money (even though people think it's tacky to ask for money). So I've been looking at getting a honeymoon registry. Has anyone used one before and can give pros/cons on using it rather than getting cash? Do you have a site you used/know someone has used and liked?
