Why not wire funds to your casino of choice, such as the Rio for the WSOP ? Revolut allows for transfers to US accounts, such as your casino's receiving bank account. Ask your casino's cage for help. After all, you are their customer .....Find out their conversion rate or wire in USD.
Also, tell your bank to raise your daily limit. I am sure that ATMs will allow you to draw up to your bank's daily limit. ATms in casinos will go to $3000 if I recall correctly.
Finally, Revolut issues a prepaid VISA or Mastercard, will they allow you to preload it and withdraw up to say $3000 per day ? According to their website, ATM withdrawals are limited to £5,000 or equivalent per day and £100,000 or equivalent per month.
