My partner and I visited during February half term during a short break in the Chilterns and we both thought the museum was very interesting. You can't miss it from the road, being painted lilac, with charaters and quotes from Roald Dahl's books. It was lovely to see the writers hut in which so many wonderful stories were composed and also the gates from the Charlie and Chocolate Factory movie of 2005.
The cafe was nice, with more memorabilia and good selection of food and drinks but my main problem was the shop. I know it was half term, but it was way too small and was hard to look at anything because you were carried along in the queue. I was also a tad disappointed because at other similar museums (Beatrix Potter/Agatha Christie Greenway House) they stamp your book as a souvinear of your visit. I asked if they did something similar here and was told no, but its a good idea! Its a shame because books sold like you would buy at WH Smiths, especially for foreign visitors.
There is a Roald Dahl trail you can do around Great Missenden and see his Grave in the Parish Church (a good walk or 10m drive from Museum), the petrol station which inspired "Danny the Champion of the World", the Post Office, The Library where Matilda went when her mom played bingo and Dean House (inspiration for the norphanage in BFG). Great Missenden is a pretty village and lovely to have a walk around and has some nice small shops, including an old fashioned sweet shop opposite the museum!!
Parking is limited to the station, a small car park off the main road in and on-street. Watch out that you put enough money on on the pay and display as traffic wardens were active! We did though.
Enjoy sampling a bit of the real and fictional Dahl and take your camera too!!!!!
