Your kids will have wonderful memories of you just being there. My mother has fibromyalgia and has vacationed with us at Hawaii, Disneyland and Disneyworld. Yes, sometimes she's slower than us or has to go back to the hotel and rest or meet up with us in the park because she can't get out of bed in the morning. But of all the memories my son has, he never talks about her leaving early or not being there. In fact some of his fav memories are ordering room service and eating "fancy" with grandma in her room. He thinks it something special that they do.
Have a wonderful trip and enjoy every minute of it!
