From my point of view, as biased as it is, this is the breakdown:
- JW Marriott: the top
- Marriott and Renaissance: full service hotels, typically with an executive lounge (which is nice when you're gold and above)
- Springhill Suites: bigger rooms (some places like Montreal, 2 TVs), with a fridge and a microwave
- Residence Inn: for the longer stays. They have a fully equiped kitchen.
- Courtyard: a good room with a restaurant. Some have fridges.
- Fairfield Inn: the lower cost variant of Courtyard. Although they typically include a buffet breakfast.
That's my nutshell summary. Feel free to PM me for more of my 2 cents.
Cheers,
