So with Amex charge cards, there's no limit but yet it still has a limit, it means charges can be approved over that amount its not a strict credit limit like typical credit cards. I had no issues. I did also split my payments to
DVC over 90 days, so I charged across multiple cards multiple times. I wanted to maximize my sub so I actually used 8 different credit cards total. If getting multiple new cards I wouldn't apply for all at once since you have 90 days to pay off the DVC loan. Amex gives card numbers immediately, but physical cards arrive within about 10 days, Chase I had my cards within 3-7 days.
