Negril Treehouse deal with Living Social

[MiShell]

Living Social deal is up $360 5 days 4 nights for 2! Escape section

Hi Gail,
A couple questions:
For transfers...will you transfer at a later date than check out if we get ourselves to Treehouse
Can you use two vouchers and stay for 8 nights
Is tax 20% and is it on the discounted or full amount

Thanks
