I completely disagree. Why use your precious vacation time doing basic dives where you follow your instructor around, remove and clear your mask, remove and replace your bc, practice fin pivots and all the other tasks you need to do? Tough it out, do your 4-5 dives in a 7mil wetsuit with lots of weight, learn the basics of buoyancy in the exposure suit and then when you go on your tropical vacation, you will have less neoprene on, buoyancy will be easier and you can spend your vacation doing the types of dives you want to do and see the things you want to see.
