hello, good day! my sister and I will be travelling to hongkong, macau and shenzhen next week. We will be arriving in hongkong airport. Since this will be our first time we do not know how to travel from hongkong-macau-shenzhen- back to hongkong or which ever is more convenient and can save us money especially the fares. Hope you can give us directions on where and how and can suggest the cheapest possible transportations and each fares so we can budget our money. Please help us also in booking the hotels. Can we just go directly to the hotel on the day of our check-in without prior reservations? And if possible can you suggest where to go the tourist attractions in the 3 cities too? Thank you very much!
