DoubleTree by Hilton Hotels in Wellington

I have just had a one night stay at this hotel and splurged on a Junior Suite which was well worth it. The room was beautiful...better than the photos suggested which is really unusual!! Due to current low staffing levels (the bane of hospitality everywhere atm) they currently don't offer valet parking and this was the low-light of the stay. Obviously I completely understand the staffing issues but.... On arrival (at approx 10.30pm due to a 4+ hour ferry delay) I was dismayed to find the doors locked but staff were available to let me in. I unloaded and my bags were taken to my room and I had to park the car myself. Other than being really tired and not up for negotiating Wellington CBD's notorious one way system to get to the car-park, this was fine and not usually something I would gripe about. The car-park is actually directly attached to the hotel which is perfect, but I had to drive around the block in a counter-intuitive manner to get to the car-park. I knowingly drove the wrong way down a 1-way St to make my life easier as it was okay to do it at that time of night with deserted streets. An hour or so later I called for room service (several times) and no-one answered the phone on any occasion. I knew they were short-staffed so no problem, I wandered down to reception to order a meal. I had the chicken laksa which was nice. The midday check out was wonderful and check-out was seamless. But I had a major issue getting out of the car-park and I'm not sure if this is my fault or the Hiltons fault. On arrival I was given an information sheet regarding the parking and this included the exit code. I committed this to memory and off I went. However, on entering the code at the car-park exit point the barrier did not rise. Traffic built up behind me rapidly and my blood pressure and stress levels ramped up accordingly. I had the correct code and on subsequent attempts to get out, tried the code followed by the # key and also tried the code followed by the tick/green light key but no dice. I tried calling reception but got no answer and was just about in tears when a kind man (about 5 cars back on a narrow exit point in a typical inner city parking building) walked down and used his card to let me out. Thank god for him whoever he was. This was really stressful as I had been on the road for 2 weeks and was about to embark on the last leg of my journey and just didn't need the stress. I was particularly annoyed they did not answer the phone when I called. I called a 2nd time but by the time I got some-one on the phone the good samaritan had let me out. I definitely had the correct code to exit the car-park but was not aware I needed to press the tick/green key afterwards (although...I did try this and it didn't work... I may have entered this final step too late because I didn't know it was needed). I can't recall seeing this instruction on the info sheet I was given. Hence...it may have been my fault...or not??
