My husband and I have separate bank accounts. We share household expenses and entertainment, and have a joint savings account we both contribute a specific amount to but then the rest of our checks are our own to do with what we please. So if he doesn't want me spending my money on a solo trip that is his problem. Seriously though my husband approves of my solo trips and I encourage him to do some things separate from me too (like his baseball games). We do go to Disney parks together as well.
