We did a trip to WDW in September 2018 and we found the temps rarely got above the low 30’s although we may have been lucky. We were also lucky with the rain, only experiencing rain about 3-4 times in 3+ weeks in Florida. A thunderstorm rolled in one afternoon and closed the pool but we had already enjoyed a couple of hours there and the pool reopened within 2 hours or so and never affected our park days. Again, maybe we were lucky as it’s a tropical climate so summer storms and rain with high heat and humidity can occur. Typical of the tropics though, they are usually afternoon storms that last for a couple of hours or so and can be good to cool things down for the evening. Just use
cooling towels, hats and drink plenty of water. We took water bottles we could refill with the free iced water in the parks.
We flew via DFW but typical of domestic flights in the USA our domestic connection was delayed so we ended up arriving at MCO about 5 or 6 hours late so make sure you have protected connections on one PNR for your flights. We called the transfer company from DFW to let them know we’d be late and they were there waiting for us (we were going to Port Canaveral first).
For a 7 night trip, I’d stick with Disney, 10 nights you might be able to do 2-3 days at Universal as well. Universal Orlando is a completely different animal to Universal Hollywood and worth it if you have the time and budget.
I booked through several places depending who was offering the best deals. I rented DVC points for our room at Disney Animal Kingdom Villas through a points broker (David’s DVC rentals). Advantages were getting a deluxe for the price of a moderate, disadvantages are you need to book months in advance, pay in full at time of booking and it is completely non refundable. Worked well for us but of course that was in the before times. For our
Disney Cruise, flights, accommodation in Port Canaveral, Florida Keys and Royal Pacific Resort at Universal we went through our
travel agent as she sourced some great deals for us. Staying at RPR also gave us unlimited express passes so we could visit the parks, do what we wanted to do quickly and return to the resort (about 10 mins walk) and enjoy some pool time or something else in Orlando (like shopping).
For our tickets we purchased the UK tickets through Orlando
Attraction Tickets and American Airlines so had 14 day WDW tickets, 14 day Universal Tickets and Discovery Cove tickets. I don’t believe AA is an option any longer. These 14 day “UK” tickets can be cheaper than the US based multi day tickets depending how many days you are looking at. Usually worth it if you have about 5 days at Disney and between 2 and 3 days at Universal, you’ll need to compare the current prices. They were delivered to us in a few weeks and did give us flexibility as were weren’t limited to a set number of days at each park so we could (and did) visit more often for a shorter period rather than having to do open to close every day.
So we booked through various places but could easily have booked ourselves. We did plenty of research so just told our agent what we wanted and when she came through with the best pricing for parts of our trip, we booked those components through her. Specialists like
Dreams Unlimited are another great option of course. Another great resource is the mousesavers.com website. Lots of info and discounts for everything from hotels to car hire.
Sorry for the long post but I hope there are some things there which help you out. Have a great trip.
