Tea ceremony is more towards cultural belief. Option 2 is workable if more modern eg. No tea offering ritual to ancestors or ancestral tablets.
I think doing the tea ceremony at the hotel is good too, just that the family and relatives need to arrive earlier, instead of their usual arrival just before the dinner starts.

Good thing is that if they know there is a tea ceremony, they will come and attend it (for face matters) and the best part, can start dinner on time because relatives are already at the venue.

I think it is best too and my wife actually wanted it that way. Because for the lady, she only need to be tired for one day.

If ROM is a separate day (usually it is), then you gotta find a new dress and wake up early to do the makeup/hair. Also if you have some friends or relatives over, you gotta buy them lunch (not that you have to, but it is just common courtesy for their time to attend).

If ROM is on the same day, more tiring but save some hassle. Still have to wake up early for makeup, maybe can save some work, can just wear your wedding dress or the same gown/dress you wore in the morning.

ROM usually is very fast. The official will read some stuff, then I do, you do. Put the ring on. Done. Most cases it takes a longer while because everyone wants to take a photo with the bride and groom inside the "swearing" room.
If you do ROM and tea ceremony right after, no need for the relatives to take photo with you during the ROM, you can tell them to wait until tea ceremony for you two to take photo with them right after serving them their tea. Everyone gets their photo. Happy days. Dinner starts on time. You two can go home and rest earlier too.
For me, I did my ROM separately, just a day before the first MCO lockdown hits.
Didn't manage to do dinner since we postponed until we got tired and the mood is no longer there. When the MCO loosen a bit, we just did the tea ceremony with some immediate family members and called it a day. Both families were okay without doing the dinner but tea ceremony is a must. For ancestors to "acknowledge" our union.

Phew, saved a lot from not doing the wedding dinner, haha.
