I do not know of other hotel programs where you can transfer airline miles into hotel points. Some airlines will let you redeem the airline miles for free hotel stays. British Airways is one such airline where you can get free stays in Marriott, Radisson and one or two other hotels using British Airways miles.

The membership reward exchange rate is pretty poor. Even with a 20% boost mentioned in the latest Notiflyer it is not a good deal. It is a better deal transferring the membership reward points to a participating airline and then from the airline into HHonors. That way you get 2x instead of 1.3x

Diners Club has had 2x promotions with HHonors but I have not seen these in a while.
