Better check if you're really even getting close to fourth night "free"
As the benefit changes and booking on "thankyou" site eliminates elite benefits here are some interesting observations - in anticipation of new system I checked 2 hotels on the ty site vs Bonvoy site:
1 First hotel alleged $94 savings was actually $30 (compare total charged on Bonvoy vs total charged on ty AFTER 4th night credit)
2 Second hotel alleged $155 savings was actually $60 (same as above)
So for giving up free breakfast, free wine, etc. possible upgrade for 4 nights - I can save $60?
So ty increases the price, decrease the benefits (no elite benefits if you book with ty) and actually save you 30% of what they claim to be saving! I'm pretty sure they are making more than this on the commission for the 4 nights.
BTW - last summer I booked a non chain hotel and it was cheaper booking directly or using agoda (or such) than booking with the 4th night credit - that is I paid LESS paying for the full 4 nights then I would have paid with 4th night credit - allegedly getting 1 night "free"!
Be careful out there - scams are all around us -----
