Is there a specific section of Beach road you recommend? I guess near walking street, right?
Late Jan I walked from Soi 6 to maybe half way to walking street a few times and there was nothing to temp me, though a lot of ladyboys.
Just keep on going up, there are sections of older women, younger, fatter, Russian, tranny's - basically all walks. They go almost up to Soi 6 (not quite) but a long way up.
Often girls go from there to the nightclubs or vice versa (the younger more attractive ones). But you can find girls everywhere, just ask them for their LINE (better if you don't outright ask if they are FL, it is almost always the case they are, or even better looking for fun).
Thai Friendly, then getting their instagram from TF is a good one too, you get to check them out. Just so many options. (always have a backup or be decisive otherwise you will be kicking yourself).
