There are a number of family friendly hotels in Singapore where cots are available on request. These hotels also have pools and laundry services. Remember that the laundry services can be pretty expensive and make sure you check the price before sending your clothes to be cleaned.
The Sofitel, The Holiday Inn Express and the Novotel Singapore are all family friendly hotels located in and around the Clarke Quay area. These hotels offer cots on request. This is a fantastic base as it has an MRT station and is located on the river and near plenty of restaurants. You can also walk along the river to the Gardens by the Bay and stop off at the Singapore Lion statue and some of Singapore’s many cafes on the way. The Mandarin Oriental is also a great option for families if you want to spent a little extra. The Shangri La’s Rasa Sentosa Resort is located on Sentosa island which is a very family friendly spot with some great amenities and activities for younger guests. This area offers beaches and play areas and is quieter and more relaxed than the city.
