I've made around 95 purchases for lodging from Skyauction and LOVE it. I have learned quite a bit. I would never bid on airfare from them since I like to control flight times and airlines to fly. Lodging deals are the best anywhere.
Each auction is different. You have to read the details carefully. Even then, the details can be misleading. They may talk about one bedroom condos that have full kitchens but later in the listing state the unit you are bidding on is for a partial kitchen. Some of the excess inventory they get is at poorly rated resorts. Look up reviews on Tripadvisor first so you know what people think.
I buy certifications to use on 7 day condo stays in the future or pay a bit more to book a specific resort that has the dates and room size I need available for sure. Certificates are emailed the next business day after the auction is won and specific resort stays can be specified by you the day after your winning bid. Confirmations are generated when you finalize your resort selection and cannot be changed or cancelled. The record stays in your account details and can be reprinted anytime.
Your information is forwarded to the resort less than 1 week before arrival and possibly even the same day. They often don't have my info at the front desk but find it on a list somewhere after a long search. For weekly condo stays (I don't book hotel or nightly stays) you are treated as though you exchanged a timeshare week.
I have had a few problems in the past that were resolved through emails. I can take up to 4 days to get an email response. I always worry needlessly since they have always fixed any issue.
In summation:
Read all the details in the auction closely, including additional fees for traveling on specific dates and processing fees.
Be careful what size unit you book. I try to stay away from one bedroom units since they can be very small and not very well appointed. Upgrades are either unavailable or very expensive so book the unit you ultimately want.
Understand any additional fees a resort may charge. Wifi, safes, resort fees, taxes and cleaning fees are possible. I have never been charged a cleaning fee for a 7 day stay.
At least 75% of the timeshares listed get poor reviews so know what you are getting into. Better resorts cost more.
The cheapest deals are 7 night stays that include taxes and service fees (except for the $20 processing fee)
If you are unhappy with a room or resort, don't expect to get any help from Skyauction. You are on your own. You will have to work things out with the resort yourself. I am always as nice as possible and if I need to be moved because of problems with a room, I try to be very kind to the desk person who is ultimately going to be the one to help fix the situation.
They are closed weekends so don't expect a response on Sat or Sunday to any emails, questions or requests.
I have paid as little as $170/week and as much as $400 per week for up to 3 bedroom condos all over the country and have never had a disappointing experience, although some properties are much nicer than others.
Remember that you are paying a fraction of what timeshare owners pay for the same stay. I keep very quiet about the deal I received when talking to others. I don't want to piss off owners and have them complain to the resort.
Any other questions?
