So...first world problem here but I've got a dilemma and while I know this is a totally subjective decision, I'd love to have some opinions! My husband and I are planning a trip in May 2018 and we're trying to decide whether we want to do a day each at Discovery Cove and Sea World (neither of which we've never visited) or if we should instead increase our WDW days from 4 to 6. I think my primary hesitation about DC/SW is the "unknown" factor. I know just exactly how much we love going to WDW and I have no doubt that we'd love an extra 2 days and would find a lot of value in that expense. With DC/SW, I only know as much as I've read/watched. I did go to Sea World in San Antonio, TX as a child but that's been 20 years ago and that park is much more of a water theme park than the SW in Orlando. My main concern is would we get roughly an equal amount of enjoyment/value out of DC/SW for ~$550 that we would out of adding two days to WDW for ~$130. Looking at the prices, it makes it feel like a no-brainer, but that $550 includes the dolphin experience at DC as well as food for the day. Plus, it's hard to assign value to experiencing something new versus just repeating parks you've visited several times before. Thanks in advance!! p.s. One other minor factor I'm also juggling is transportation. We're doing a short cruise at the end of this trip and the need for a way to get to DC/SW pushed us to decide to rent a car for the whole week. Since we were going to need transportation to DC/SW and we'd like more independence on when we get to Port Canaveral plus the ability to stop somewhere and buy a few groceries...all weighed together, it made a rental car seem like an okay splurge. However, if we didn't do DC/SW, I think we would also not rent a car and would use Disney transportation the whole time. I think probably the costs here will come out a bit of a wash, but it generally just throws another kink in my plans that I had thought were rock solid.
