I had a booking for one night at HI Andorra, so I've been more than happy to cancel it and book 2 PB nights instead. I haven't been able to choose a room for 4 pax though, only standard ones for 2 are available, but as a Plat and a repeat guest I guess that they'll be able to fix it.
As a side note, this is the first time that the hotel has been on the PB list. Until a few months ago it used to be CP Andorra. Strange that a refurbishment has meant some sort of downgrade to a HI, although it remains a 5* hotel (by Andorra standards). Given that the high season in the country is the winter, it's not surprising that they've joined the list this time.
Yesterday there was availability on every weekend of July at HI Krakow; however today some dates are not available. It should be out of the list soon...
