Here are some credit cards that currently have increased bonus offers compared to their standard offers:
Marriott Visa Signature from Chase
There is currently an offer for 80k bonus points for both the personal and business cards if you spend $3k in the first 3 months of account opening. You must not have had this card in the past 24 months to get the bonus. The personal card has an $85 annual fee and the business.card has a $99 annual fee. For both cards, you will receive an annual night certificate for a category 1-5 hotel.
To see how far these points will get you, below is their award chart. For extended vacations, you can get a 5 night stay at a Marriott hotel for only the cost of 4 award nights. I’ve used this option several times to get the most out of my points.
Here is also a helpful post of how to redeem your free night certificates with Marriott.
Another unique thing about Marriott is their hotel and air packages where you can redeem your points for a 7 night stay in a selected hotel category plus you can get airline points. Many have used this strategy to get the Southwest Companion Pass as these transferred points will count towards it.
Hilton HHonors cards from Citi
There are currently 2 card offers with increased bonuses, the Hilton Reserve Card which gives you 2 weekend night certificates with a $100 statement credit when you spend $2,500 within the first 4 months of card opening for a $95 annual fee. It also comes with Gold status which gives you free breakfast at hotels (my favorite part). Another offer is the Hilton Visa Signature Card which gives you 75k bonus points after you spend $2,000 within the first 3 months of card opening with no annual fee and Silver Status.
To see how far your points will go, here is a Hilton award chart:
Hilton also has an option to redeem 5 nights for the cost of 4 award nights for Silver, Gold, or Diamond members. Luckily both credit cards give you status.
