Hello We are booked to stay here and have few questions for past guests. Not all questions are about the hotel, which we do not have major worry but more other things. -How is the weather and temperature in early March in Shanghai? -We are told that all Shanghai is high tech and cash less society now. For tourists, do they have to do the same too? Can we pay cash for restaurants or other things? -Phone call->we prefer phone call to check on family (old parents) in Canada who do not know how to use smart phone so any advance options is out. Can one buy a "phone card" and use their own phone to call back to Canada? Or use hotel phone? We worry that using hotel phone always seems to create lots of charges. -For about one week trip, some lunches and all dinners, how much cash average a couple would need? (we are not talking gourmet meals here, just regular restaurants) We are told $300/person. thanks.
