GOTIME
The only site in the Expedia network that I can find with a code valid for stays post 30 June 2016. Hotels.com, Expedia, Venere - all their current codes are only valid til 30 June.
Don't forget Cashrewards. Also useful they will credit you Orbucks immediately to use towards next booking, unlike the others where you need to build up over time.
As always compare prices with other sites as prices could be higher even after discount. Also note that they bill in USD.
