OP- I could have written your exact post.
We are leaving tomorrow for DH conference and have a 1 and 3 yr old. I am getting pretty nervous about taking the 2 little ones by myself, but luckily DHs conference is done by 1pm each day, so I have reinforcements for much of the day.
When I get back, I can give you more detail about how it went and what I would do differently, but here are some thoughts in my pre-trip plan
*we are staying at a monorail resort. I figure that most of the time that I will be alone at a park will be spent at MK. I know that I will not be able to fold up a double stroller and lug it onto a bus while holding a 1 yr old DD in my arms and making sure 3 yr old DS does not take off running as he is known to do. Rolling the stroller onto the monorail is a huge plus.
*Character breakfasts- avoid buffets. How would you handle a tray and 2 little ones at the same time? Ohana is family style breakfast. Garden Grill is family style too, but I don't think they do breakfast anymore.
*I plan to use a hip hammock for 1 yr old and toddler harness for 3 yr old for lines. (please no flames- my 3 yr old can run faster than me)
*I plan to start very slowly with regards to ride intensity for the 3 yr olds sake. Of course, we are staying away from all the height restricted rides for obvious reasons, but we are also shying away from HM, POTC, and Snow White the first day for the fear factor.
*Scout out the play areas where your little ones can run free a bit- Pooh's Playful Spot, Tom Sawyer Island, Toontown play areas, HISTK playground, Boneyard, etc
Like you, I am worried about the safety factor in 2 kids/1 adult. What if they both start furiously squirming away from me while on a ride? I am staying awake nights thinking about the headlines of a drowning on IASW or plummetting off Dumbo. I'm sure it will all be fine, but a mother is gonna worry anyway.
I can let you know how it went upon our return. Happy planning!
