Striking opponents, for me, is not a very "Aikido" way to do fight. Of course, Aikido has some "striking". Striking as in to distract or disable opponents only. I'm still having troubles since I only started recently. But the bottom line is, if striking is the ONLY way to finish the fight, then I say go for it.
About sight seeing, I recommend Bohol. I just went there last year and the scenery was just spectacular and the weather was just great. However, after the Ondoy incident, the climate has been very weird. In the past weeks, it rains hard, it gets super sunny, and it becomes cloudy with nice winds. All in one day.
Umm... Mano Mano is just the empty handed component of Filipino Martial Arts.
