As i know except the one day trip, Liveaboard trip at least 3days 2 nights. Even from khao lak, u need spend around 1 and half to 2 hours by speedboat to reach simila area. So u will disappointed when u just go there for 1 day trip, waste so many time on speed boat.
Some liveaboard can pick u up in phuket at night time (mostly), your dive should start on the day after. Some pick u up in khao lak, mostly in early morning.
If your wife is not certified diver, she will be boaring because the main activity is scuba dive. Some dive sites are not suitable for snorkeling.
U can ask her to take a open water course at the same time, then u can enjoy more and she can go diving with u next time. But, some liveaboard will sepreate divers into 2 groups, for experience divers aow, the liveaboard will go anywhere of similan; they will group some new divers and somebody who want to have a dive licence together. The dive sites are some shallow dive sites only, current is weak, easy for a uw training. So the dive sites are limited in somewhere only.
There are so many liveaboards. U can try to search more online.
