Hi Jan

We stayed at the Athens Hilton and were really pleased with the property and service. If you're a Hilton Honors member, see if you can redeem points for your stay. Also look into upgrading to Club, if possible. We were upgraded and the upgrade included breakfast. Room was really nice and spacious, offering a beautiful view of the Acropolis.

Rather than request a rollaway, ask for a double/double accommodation (two double beds). If someone doesn't mind sharing a bed, that may work for the 3 of you.
