If I recall correctly... while the promenade is not a wraparound... there are doorways forward and aft and you can walk through to the other side.... forward is near the forward elevators...just outside the theater BUT on the aft end there is a door on the starboard side..but you can't go straight across to the other side... if you want to do that you have to cross a bit closer to mid ship.... near the other elevators. If you just want to do a leisurely stroll vs a serious walk... I think you can still do it... you do have to deal with some smokers... but you are only passing by. I like to get up early and walk the track up on deck 14...but later in the day the crowds make it harder to get a steady pace. Deck 5 is generally quiet and not that windy... but as noted earlier..often sections are roped off for maintenance of the lifeboats and other items.
