if price is the concern, you can always choose a cheaper hotel. andaz and grand hyatt are among the more expensive ones and there are many very good and cheaper options

if you prefer for everyone to stay in the same room, many hotels also have options that accommodate 4 pax, including andaz and grand hyatt

for the above options, you can easily find them via OTAs

as mentioned by yosithezet, you can also consider service apartments, which is probably more similar to residence property, but i do not think you can redeem points for these
