Oil & moisture are your enemies.
That said, they effect people differently.
Its hard to say how long anyone will get a bond for no matter what method of attachment or products they use.
A lot will depend upon whether your skin is oily or you sweat a lot.

I wouldn't worry too much about the texturizer now that you've washed it off.

2 brands of tape that get recommended frequently for swimming are STICK-IT tape and the blue backed tape.
For glue, Oil Resistant White Glue (ORWG) might be your best bet.

Just make sure you do a brand new attachment before you set off on your holiday and there is a less than 1% chance of it coming off whilst snorkelling.
