The staff at Sisouk were extremely helpful.
I booked in here for 1 night before starting the Vat Phou cruise and for one night when the cruise finished.
The Vat Phou cruise was also booked, and fully paid 4 months in advance, through Expedia. But on arrival in Pakse when waiting for the pickup from the hotel was told by the Vat Phou company that Expedia had never informed them of the booking, never sent the money, and that there were no cruises for the next 2 weeks.
Sisouk arranged a TukTuk to get me to Vat Phou temple and allowed me to change the dates of my hotel booking with them for no charge. So 5 stars to Sisouk. Really helpful people.
Expedia - 0 stars. Although they have processed a refund for the cruise no apology offered yet which is just exceedingly poor customer service.
