To go to Cappadocia and Pamukkale, you can take a domestic flight from Istanbul since they are located far away from the city. There are multiple airports for each destination, and the prices vary depending on the airline and time of booking. Alternatively, you may take a long-distance bus that usually costs around $30-$40 per person with a travel time of approximately 12 hours.
If you have more time, it is recommended to spend an additional day in Istanbul to see the Topkapi Palace and the Basilica Cistern. For a more extended trip, you may add a day to explore the picturesque coastal city of Bodrum or relax in the pristine beaches of Antalya. On the other hand, if you have less time, it is suggested to skip the Cappadocia hot air balloon tour and instead spend more hours exploring Pamukkale and Hierapolis. It is also recommended to schedule the Turkish dance show and kebab dinner earlier in the evening to have more time to relax after.
