Thinking of our last vacation before babies arrive

We were really late in planning for this. We initially planned to go for a cruise (Star Gemini) but only to find out that once Felin reaches 24th week, the cruise will not accept us onboard. We then thought of going Batam or Bintan Club Med only to learn that we cannot board the ferry once we reached 28th weeks, unless with Doctor's certification. As we need to complete our antenatal class, it will be over 28th week by then. I then thought of going Malaysia Desaru Pulai Resort but Felin told me that she is not comfortable if the place does not have a proper hospital. Felin is also not comfortable travelling on a plane at this stage. That left us with only a Staycation in Singapore.

One place we thought that we can be furthest from Singapore island will be Sentosa.
The range of Resort World, Festive Hotel, Hotel Michael, Movenpick, etc... are far too expensive and cost between $450 to $600 per night. If we are going to stay 2 nights, it will cost us nearly a thousand dollars.

Then I thought of Costa Sand Sentosa which will cost lesser at about $200/night and moreover I can use quite a bit of my linkpoints to pay but I afraid Felin may not fully enjoy it because it is nevertheless a Chalet and not hotel. The closest I can think of will be this Siloso Beach Resort which I can book the Roof Garden Suite at $325/night. The seaview seems good and the room is quite big at 50sqm. Actually, if we chose the superior rooms, they are actually even cheaper than Costa Sand at only $193/night.

Just that the reviews are not as good citing the services wasn't up to standard or the place a bit run down and breakfast not so nice. Not sure whether to just spend the money and go to a top notched hotel or just go for an okay one.

Other options I have will be the Amara Sanctuary and the Singapore Resort and Spa Sentosa which is managed by Accor. Their standard seems to be better than Siloso Resort but they are pretty out of nowhere on the island. To get out, we need to take their shuttle bus and on review, the shuttle bus seems to take forever to arrive. The top picture shows the Amara Santuary and the below one shows the Singapore Resort and Spa. Price wise, they are about $300/night as indicated in Agoda for their standard rooms. Well... Just some ideas in mind and need time to consider...
