Yes to both, you can check in at the Executive at either property. At the Conrad though, you most likely will have to ask at the front desk if you can check in at the EL, and they will then escort you op to the EL, where as at Hilton its more than likely you will be escorted up directly to the EL. Both properties offer breakfast in the EL, though the choices will be rather limited.The choices at the restaurants will be more extensive with more local/asian options. I prefer the restaurant in the Hilton over the Conrad, its larger with more choices.
