You have to take a car to reach the desert area from the main areas of Dubai. I doubt you can park your car anywhere for free. Instead why don't you spend just around 80-120 Dirhams per person and enjoy the evening with pick up from hotel or apartment, dune bashing, sand skating, music and food. It's all included in the price and well worth the money. If you just want photos to show to your friends, then use a green screen in your room itself and edit it to make it look that you went to the desert.

Hi jo I do not remember being served alcohol ..

Dear Kishor, you can ask the driver to avoid much jerks. You can simply take a drive in dunes at a lower speed i guess. Totally dropping this activity from your itinerary is not a good idea i guess as evening in camp is good and an experience to have. Also the cars which they use for safari are good ones like land cruiser so its not as rough as we have in india.

We were allowed entry from a smaller gate where tickets were also being sold & there was a big space for bus & car parking. Entry was thru this gate only. Can't remember whether it was gate no. 1 or 2. but it was not a gate with big doors as you can see in pics of miracle garden. Hope my answer may help you a bit. You can ask more, if i can help i certainly will.

Please the question in English please

Well, the dune bashing can be a bit rough experience. Its similar to sailing in a ship caught in a storm. I would suggest you consult your cardiologist before planning the trip. If you would like to go then it would be better to sit in the middle seats of the vehicle and tell the driver beforehand that you would like a milder version of the trip.
