Hello Mr Boss. I can help you with the Hyderabad part. Where exactly is the house warming ceremony in Hyderabad? You have many temples and tourist spots. Some of them are:
(a) Birla Temple (Near Hussain Sagar Lake)
(b) Ramoji Film City
(d) Qutub Shahi Tombs(close to Golconda)
(f) Necklace Road(evenings, The other side of Hussain Sagar lake)
(g) Chowmahalla Palace
(h) Sanghi temple (31 km from Hyd)
(I) Bawarchi Hyderabad Biriyani (R.T.C X roads) if you are an avid non vegetarian. Yummy biriyani.
you can even try Paradise Biriyani.
You can select the places depending upon the area you would be staying for that particular day.
Well I prefer personal vehicles to get around. You can opt for auto rickshaws too but quite expensive(do ask them to reduce the prices. Very few come on the meter. Others just say a number which they like). I don't prefer buses so I would not recommend to you too. You would unnecessarily get tired. Its better you can hire a taxi for a day. They charge you for first 8 hours/150km and then per hour/km. This would be a better option. You have many cab services which you can easily book online too.
I can help you with anything if required. You can PM me or my contact number 09989743720
Hope you have a nice time in Hyderabad!
