Sonesta Hotels are fine. Sonesta chain? I wish they were better. What a pain. Be aware if you want to search hotels on their website, you have to price them ONE AT A TIME (which may mimic your website name, but sucks when searching). You can’t just get all their hotels in an area and prices for dates --can you think of any major chain where searches work like that?? I suspect they are living on the loyalty of folks like me to hotels we liked when they were IHG, Marriott, etc. Phone app? Not yet. Have a lot of points and want to book online? Nope. You must, get this, Fill in a form and submit and hope it is accepted. What? It’s 2021. Nearly a year since your post. They added lots of hotels. I have points, I like their hotels in areas I need hotels. But such a pain I cringe any time I book with them. All other chains make it easy to compare within the chain in an area, and have an app, and let you book online with your points any hour of the day instantly if rooms are available. So FYI before you get as involved with them as I did. I have to imagine this will change. But not so yet. That you are a travel site and you don’t mention these limitations is a bit odd. Suggests you have never tried to test-book anything even to see how they work, skim their website (where the silly way of cashing in your points is apparent), etc. Not normally like you, but you did ask your pool of followers.
