Satnav users

Since our building is new, our address and postcode does not yet appear in many satnav systems. We therefore suggest that you enter the address or postcode of the local Holiday Inn, which is the nearest building to us, as your destination.

Holiday Inn Express Hotel Southampton – West
Adanac Park
Redbridge Lane
SOUTHAMPTON
SO16 0YP

At the big roundabout immediately after the M271, take the second larger exit for Adanac Drive, not the first small exit for the Holiday Inn as directed by your satnav. Our building will appear straight ahead after a couple of hundred yards.
