It was initially hard to draft up an itinerary fit for the elderly. My dad is 66 and my mum is 59. So a lot of patience is required for elderly walking pace as well as endurance and stamina. :-) I'm quite happy though that the haze cleared up on the day we arrived and continued to do so until they left.
In summary I made the below itinerary for them. They arrived and checked in to the hotel around 4+ pm so they weren't able to visit my friend Ange for a tour in the National museum of Singapore.
Day 1 late afternoon - Bugis Junction, Bugis +, Bugis Street
Night 1 - MRT to Chinatown, Smith St, Temple St (souvenir shopping), saw the Hindi and Buddhist temples, (the food street is closed by the way for some construction), ION Orchard, Paragon (toys r us to buy something for their Grandchild - Leonardo Ninja Turtle that was out of stock in Trinoma haha they wanted to buy all four to give), H&M
Day 2 - Marina Bay Sands, Gardens by the Bay, Marina Bay The Shoppes, Din Tai Fung lunch, Arts and Science Museum, Stomp at MBS Theater
Night 2 - MBS Lights show, Helix Bridge, Esplanade, Merlion
Day 3 - Singapore Flyer, Singapore River Cruise, SEA Aquarium in Sentosa, Vivo City, MRT to Ang Mo Kio
Night 3 - Night Safari
Day 4 - National Museum of Singapore, Airport
Because of the light haze and heat (which my mother complained about), I had to improvise with the tour. We weren't supposed to go to the SEA aquarium. We were meant to go to the Singapore Zoo and River Safari then Night Safari as those attractions are covered by the attraction pass my brother bought for us three - but because of the heat and my mum and dad not having enough endurance to continue for longer walks, I had to improvise.
I wasn't able to ask them what they enjoyed most but I think the tour was just right for elderly people. It would be so much better had I owned a car to drive them around :-). Because of the difference in their interest, and my mum having visited before, I had to put in more stuff my dad would like. My mum did enjoy the National Museum of Singapore because of the audio guide I think. She's not big on reading history but she does like reading news or the Showbiz magazine in the PH - so listening to stuff she saw interesting was a good experience for her.
Stomp I think was also a different experience that they both enjoyed as its not typical for them to get to do stuff like it. So, for future tours I'll suggest to see shows in MBS whatever is playing. I mean, where else can one go to see them? Australia? London or New York are the only places I can think of.
It feels oddly satisfying to have spent for them. But, before we parted, my mum and dad gave me some sort of gratuity lol. I only expected them to pay back for the food or some entrances we went to as their hotel, flights and activities were funded through crowd sourcing (hahaha by me and my siblings). I was surprised after seeing what they gave...maybe it's their belated birthday gift - that's what id like to think. Now I wish I can tour them more! They paid me back for everything and more after counting. I love my mum and dad! And I love being the youngest offspring!
