If you are a family of 3 or 4. I recommend to to look for Dubai tour packages of 1 lakh 30k inr because if you are 3-4 people you need to have a hotel room for 4 days that will cost 600AED per day that equals 4x600=2400aed. Traveling inside Dubai will cost you around 500 aed x 4 = 2000aed (maximum) - per day. Then add your other expenses that will come around 7200 aed= 129600 inr. Go for Dubai holiday tour packages that covers most of your famous tourist spot and well covers your budget. Keep the flight prices at check! https://www.tripoto.com/dubai/tour-packages
Ordinary HRTC buses to McLeodganj are safe for the most parts but won't be comfortable after they cross Una and the hilly terrain starts.
i would recommend going for a pvt bus and travelling during the day as then your sleep won't be hampered and you will enjoy the stay.
Your tour package should include rolling hills of Munnar and don't forget to include a stay in house boat in the placid backwaters of Alleppey. Visit the famous Kovalam Beach. Wayanad is again a place you should not miss because how beautifully the place has been nestles and the road trip from Bangalore take you through forest area. Kumarakom, another gem. And if you want to experience Wildlife Sanctuary, you will love Periyar Wildlife Sanctuary for sure. https://www.tripoto.com/kerala/tour-packages
