i recommend Bali and Morocco and Greece : here is the reason
- A trip to Bali doesn't come cheap — but it is somewhat budget-friendly during the autumn months. In late September and October, summer crowds depart and this Indonesian island transitions from dry season to rainy season, making it a good time to find bargains at resorts
-Greece has it all. It's not a cheap destination, but fall is a good time to save a few dollars if it's on the bucket list. Even luxury accommodations lower their prices in autumn as crowds thin and the broiling summer heat abates.
Morocco : fall offers lower prices and more temperate weather -- expect highs around 80 in September and 70 in October in Marrakesh. Don't miss getting lost in that city's atmospheric Medina, or old city. Farther afield, visit the blue city of Chefchaouen and enjoy a camel trek in the Sahara now that the heat is dwindling.
there is new website called book2trip.com for vacation rentals that offer many lists on those three destination
