Ceasers Rewards via Status Match

Connors Recommendation

Focus on what hotel brands you like to stay at. Upgrade status can be achieved by pretty much any hotel with with their credit card. With free award nights I like doubling up on cards so I know that at a minimum each year they will give me a weekend trip. The best point value and big spender program is Hyatt.

Hyatt - best for big spenders, most rewards to earn

Hilton - best free night rewards can be used at any property

Marriot - two tiers of credit card rewards

Wyndham - great for Ceasers match easy top status

IGH - great cheap fourth night free option

Radisson - best rewards for staying at progams hotels
