Hi there I found a cheaper way to become caesars diamond than founderscard. I takes some time but it worked for me. You can buy the ibis business card online for the equivalent of 90€ (or 65£ for uk residents). One of the perks is that you become instant gold member with le club accor hotels. You can match this status to Hilton honors gold on their website. ( you might need proof of a stay, in this case book some cheap Asian hotel from accor) (I actually had proof of previous stays) Once you are hilton gold, you match to Wyndham diamondm which can be matched to caesars diamond. The waived resort fee, 100$ dinner and show tickets are worth more than the fee for ibis business.
