Need advice on tampons

I'm 26 and I've never used tampons before as I've used pads since I started having my period. My family and I are planning a trip next month and I'm considering trying the tampon as I will be on my period. What do I need to know about inserting a tampon the proper way? Do i need to still wear a panty liner or pad with the tampon for extra protection or will I be good with just the tampon? Also what are some good brands of tampons? Thanks ladies.
