Hi, we have been to Florida 8 times over the last 25 years, but have always stayed in a villa, with car hire. Our autistic son is 30 in January and as it is his favourite place on earth we were thinking of surprising him with a 7 day trip to just do disney. We spent 18 days there in March this year so, we were thinking low budget! Hotel with free disney shuttle would be helpful. Any ideas on good hotels to try? Needs to have one room for all three of us, preferable with one double and a single, or two doubles. No sofa bed, as he is very tall. Looking for January 2020. Have found on Perfect Holidays 7 nights at Red Lion Hotel incl breakfast and flights with Delta for £855. Anyone stayed there?
