Hello Mike!
Assuming that your are staying at a
Walt Disney World Resort hotel, you should take advantage of the
Extra Magic Hours benefit. On select days, a designated park will be open earlier or later than the regular posted hours. There is no charge for this benefit so take a look at the information I provided you. I would also encourage you to look at the
Park Hours for your dates of travel. This will help you determine which park(s) is open later on your desired day. In any case, yes, I would absolutely recommend that you purchase the Park Hopper ticket option. This will allow you to visit more than 1 major theme park in the same day.
Feel free to write back to me with any additional planning questions. I am happy to help.
Until then, I wish you a truly magical vacation!
