Spreading your money between multiple banks creates similar mental, accounting, and tax burdens as a simple investment would. Plus my "a lot" comment wasn't specifically connected to short term CDs. If you are going to let money sit for years, short term investments like that are the worst for growth second only to keeping everything in cash. That approach should only be taken by the most risk-averse people or people who need liquidity. Even still, OP is probably missing out on 5-figure potential gains by just doing nothing with over $250k+ for years. "A lot" is relative, but that is decent money that OP is effectively losing.
