4-5 star hotels generally have a cut-off time beyond which the guest is supposed to be "registered" to stay overnight. This varies from hotel to hotel but it is generally around 9pm.

Before that time, FLs may come in and visit you without being registered. I have done so quite successfully in many 5-star hotels locally though my favorite are still the ones where the guest rooms can be accessed without walking through the main lobby

Shangrila Garden Wing, Hotel Jen, Shangrila Rasa Sentosa are just of the many examples. Find out about your proposed hotel layout and you will know the answer!
