Spikenard - I just confirmed with GWP yesterday.
Junior Suite and 1-bedroom suite - By one bedroom suite, do refer to the poolside suite or the 1 bedroom suite. In GWP, these are 2 difference categories. If u are referring to the poolside suite, I have seen both this and the junior suite and both are pretty similar. The poolside suite is exactly the same as the junior suite, except that the poolside suites are on the ground floor with direct access to the poolside. I personally hate ground floor rooms, so I'm okay with this. Being in the hospitality industry myself, I doubt GWP, or any other hotel, for that matter, will promise a complimentary room category upgrade of 2 categories or more...
Parking coupons - The car park is outsourced, hence GWP cannot get additional parking coupons. Like another GWP btb, I asked for this and got rejected as well.
Although I did try asking for some extras, I thought the package is quite comprehensive in itself already. The coordinator also extended some extras to us without us asking for them, which we appreciate.
As for promptness, the first coordinator that I dealt with was unresponsive. So I requested for someone else, who is wonderful and always prompt in replying within 24 hours. Her name is Mei Fung, if need be, u may approach her?
The coordinators are really busy now, apparently, as they also manage corporate sales and they are v busy right now with the Airshow.
