Saw that Costco Travel is offering a solid 'deal' for a five night stay package. Sounds like the 'upgrade' via TSU and/or Globalist is negligible, so sacrificing that by booking 3rd party is not that bad. Just confirming the trade-offs:

- Would be sacrificing the Hyatt point earning (25+ points / $) plus the double night promo and would not have 'Club' access.
- Would be saving ~ $700 (plus Costco cash card)

Usually not one to forgo the status / point earning, but 33% off the Best Available Rate is enticing to say the least.
