Way off? No.

But keep in mind that it is only really more accessible if you can take the train to/from the airport -- and that becomes difficult if you have a lot of luggage (carts can not be used in the train stations).

If you are going by taxi, the prices will be no different no matter which hotel you go to (roughly about $30).

In that case, you might want to check the price of the Sheraton Moriah before deciding which hotel to stay at.
