We are going to Prague for 5 or 6 days in June. We have enough hotel points to stay for free at either the Hilton, IC or Sheraton. I am Hilton Diamond, IHG Platinum (and could buy the Ambassador Program since I will be there over the weekend), and SPG Gold (with Starwood Business cc so I would get free club floor access if they have a lounge). Which hotel would you recommend and why?A river view room would be lovely if any of these hotels have that. And I would prefer a luxurious hotel rather than one feeling worn down. It looks from the pictures that all three hotels are modern though I prefer a more historical hotel. Thanks in advance for replying!
