Thai Hotels Association figures show gains for Phuket's five-star and four-star properties, with Phuket three-stars not faring quite so well.
June bookings overall for Phuket are up 5.67 percent to 66.3 percent, the latest THA statistics show.
The strongest surge appears to be in Phuket four-stars, with the 84.85 figure for April up 12.27 percent and the May figure up 4.81 percent to 59.51 percent compared to last year.
The Phuket five-star rate stood at 56.82 percent in May, up 2.12 percent, while April's Phuket figure was 77.18 percent, up 7.19 percent.
The Phuket three-star market is the least promising, with the May figure of 46.02 percent up just 3.25 percent on last year and April's figure of 65.01 percent down 7.21 percent on 2011.
A spokesperson for the THA (Southern Division) attributes the looseness of the three-star figures for Phuket to the increasing number of apartment blocks that are being rented out, in some cases illegally.
Data compiled by STR Global for Phuket also shows strong gains in May, with the regular rate being paid on Phuket rising 10.5 percent to US$103.71, putting the island behind only Tokyo (up 21.6 percent to US$188.20) and Beijing (up 12 percent to US$115.05) recording bigger increases in the Asia-Pacific region.
