No need for bubble wrap if you have enough clothes to cushion with and only carry a couple of bottles. Just in case, put the bottle in plastic bags. Then wrap in clothes about an inch thick. Then wedge the bottles in tightly, stuffing rolled clothes in between them to keep from knocking into each other or any other hard object you pack. Cushion all sides and use shoes strategically as a shock deflector. Use the packing straps inside your suitcase to secure everything together to prevent shifting. The bag needs to be packed full so ther is no room for stuff to shift.
