We have been to marmaris the past 2 years and have loved it!
We did go all inclusive but the food is cheap and £700 will be plenty. We took £300 for a week for 4 of us, had days out, bought lots of goodies and came back with a bit extra!!
The jeep safari is fantastic as is the trip to turtle bay and the mud baths (id recommened it).
Couple of tips for you:
*Book trips along the beach front and the shops - so much cheaper than the reps!
* Dont change money in the hotels - very expensive.
* Be careful on the day trips - when we went to turtle beach we had to empty our bags when getting on the boats and take out all the drinks, we had so we had to buy them onboard, v crafty as you have no choice to buy them when you are in the middles of the sea lol!!
* If you want bread and bits when you get there the big supermarkets are brilliant and really cheap! We went AI but still bought a few bits for the kids - biscuits, bread, crisps etc etc.
* Dont take fruit off any guys walking along the seafront. They normally walk along with a punnet of strawberries and offer you one. If you take one, they follow you and dont back down until you buy the punnet at a ridiculous price. Just politley say no and continue walking.
*The 99p english cooked breakfasts at all the resteraunts ARE 99p but they will then charge you double for the drinks to get there money back!!
Have a fantastic time, Im very jelous as we arent going this year!! x
