Hello Michelle,
So glad I can help answer a few questions for you regarding your upcoming Disney trip! You must be so excited!
The average high temperatures for that week of September is in the low 90 degrees Fahrenheit, so you'll have plenty of opportunities for time in the pool!
Because it will be so warm out, renting an electronic convenience vehicle (ECV) for your Mom is a good idea. They are available for rent from various locations at Disney World for $50 a day. To find out where on Disney property you can rent an ECV, click
here. But if you know you will need an ECV each day of your visit, you might want to check out some of the places in Orlando that will deliver scooters to your hotel. My family has used Walker Mobility in the past and were very happy with them. The wheelchair was delivered to our resort. And we were able to leave the wheelchair with Bell Services for pick up when we checked out.
As for your last question, all of the Disney Resorts, including
Caribbean Beach Resort, have high speed Internet access in their rooms. At last check, I paid $9.95 for 24-hour period.
Hope this helps! Happy trip planning!
